Description
技术领域technical field
本发明涉及岩土力学实验技术，尤其涉及一种仿制天然裂缝岩样的人造实验样品制作方法。The invention relates to rock-soil mechanics experiment technology, in particular to a method for making artificial experimental samples imitating natural fractured rock samples.
背景技术Background technique
天然岩体通常会经受复杂的地质运动而在其内部产生许多形貌各异的裂缝。岩体大多沿着裂缝面发生破坏，而裂缝面内的流体流动能力也远大于岩石基质，因此裂缝对岩体的变形性质和水力学特性有着重要的影响。在地面和地表开展的各类岩体工程，如隧道、边坡、洞室中，裂缝影响着各类工程的稳定性和安全性。在开发深部地层的油气资源时，岩体中的裂缝又影响着钻井效率和油气藏开发效果。同时众多学者的研究均表明，裂缝的具体形貌进一步决定了其对岩体性质的影响，因此研究裂缝形貌对岩体性质的影响意义重大。Natural rock mass usually undergoes complex geological movements and produces many fractures of various shapes inside it. Most of the rock mass is destroyed along the fracture surface, and the fluid flow capacity in the fracture surface is much greater than that of the rock matrix. Therefore, fractures have an important impact on the deformation properties and hydraulic properties of the rock mass. In various rock mass projects carried out on the ground and surface, such as tunnels, slopes, and caverns, cracks affect the stability and safety of various projects. When developing oil and gas resources in deep formations, fractures in rock mass affect drilling efficiency and oil and gas reservoir development effects. At the same time, many scholars' studies have shown that the specific morphology of cracks further determines its impact on rock mass properties, so it is of great significance to study the impact of crack morphology on rock mass properties.
目前针对裂缝形貌对岩体性质的研究，主要是天然裂缝岩样在不同的应力、温度、流体条件下的裂缝法向闭合实验研究和裂缝切向剪切实验研究两种。由于工程需要预测不同条件下同样一个裂缝对岩体性质的影响，通常需要针对同一天然裂缝岩样进行多次不同实验条件下的实验。At present, the research on fracture morphology on rock mass properties is mainly two kinds of researches: the normal closure experiment of natural fracture rock samples under different stress, temperature and fluid conditions and the tangential shear experiment of fractures. Because engineering needs to predict the influence of the same fracture on rock mass properties under different conditions, it is usually necessary to conduct multiple experiments under different experimental conditions on the same natural fracture rock sample.
由于自然界中不可能有表现形貌完全相同的裂缝面，因此工程中常常直接使用同一裂缝岩样进行多次不同实验条件下的实验。但大多数裂缝岩样在经历了第一次、第二次实验后，其裂缝表面会被磨损，形貌发生改变，所得到的实验数据并不能真实反映原始裂缝对岩体性质的影响。此外，地面和地表岩体工程可采取原位实验和室内实验，取样较为方便。而深部岩体则仅能通过成本高昂的钻井取芯来获取进行室内实验的实验样品。因此许多学者和工程师都采用力学性质和岩石相似的混凝土、水泥砂浆等材料浇筑成许多具有相同裂缝形貌的边长在50毫米到300毫米之间的长方体形人造实验样品来进行实验。这样可以保证每次实验中的人造实验样品的材料性能基本相同、裂缝的形貌基本一致，实验结果也更加真实可靠。这种浇筑人造实验样品的方法被广泛采用，促进了裂缝岩体性质的室内实验研究的发展，得出了许多宝贵的结论，但也存在一定的不足之处。Since it is impossible to have the same fracture surface in nature, the same fractured rock sample is often directly used in engineering to carry out experiments under different experimental conditions. However, after the first and second experiments of most fractured rock samples, the surface of the fracture will be worn away and the shape will change. The obtained experimental data cannot truly reflect the influence of the original fracture on the properties of the rock mass. In addition, ground and surface rock mass engineering can adopt in-situ experiments and indoor experiments, and sampling is more convenient. The deep rock mass can only obtain experimental samples for laboratory experiments through costly drilling and coring. Therefore, many scholars and engineers use concrete, cement mortar and other materials with similar mechanical properties to rocks to pour many cuboid-shaped artificial experimental samples with the same crack shape and the side length is between 50 mm and 300 mm for experiments. This can ensure that the material properties of the artificial experimental samples in each experiment are basically the same, the appearance of the cracks is basically the same, and the experimental results are more real and reliable. This method of pouring artificial experimental samples has been widely used, which has promoted the development of laboratory experimental research on the properties of fractured rock mass, and has drawn many valuable conclusions, but there are also some shortcomings.
目前浇筑制备人造实验样品的方法可细分为以下三种。The current pouring methods for preparing artificial experimental samples can be subdivided into the following three types.
(1)直接浇筑方法。在现场获得含一对裂缝面的岩体样品后，对其进行切割加工，获得两块仅一个面为裂缝面，其他五个面为平面的长方体岩样。将这两块岩样都按照带有裂缝面的一面朝上放置，并在四周用特定尺寸的平板围起来组成浇筑盒，以提供浇筑的空间。在配置好水泥砂浆等浇筑材料后，直接在天然裂缝岩样的裂缝表面上进行浇筑。如果天然裂缝岩样的两个裂缝面耦合度较好，浇筑所得到两块浇筑体即可作为人造实验样品进行实验。而如果天然裂缝岩样的两个裂缝面耦合度较差，则需要将浇筑所得到的两块浇筑体作为中间件，以中间件为模具再进行一次类似浇筑才能得到实验所需的人造实验样品。(1) Direct pouring method. After the rock mass samples containing a pair of fracture surfaces were obtained on site, they were cut and processed to obtain two cuboid rock samples with only one surface as a fracture surface and the other five surfaces as planes. Place the two rock samples with the side with cracks facing up, and surround them with slabs of a specific size to form a pouring box to provide a space for pouring. After the cement mortar and other pouring materials are configured, pouring is performed directly on the crack surface of the natural cracked rock sample. If the coupling degree of the two fracture surfaces of the natural fractured rock sample is good, the two poured bodies obtained by pouring can be used as artificial experimental samples for experiments. However, if the coupling degree of the two fracture surfaces of the natural fracture rock sample is poor, it is necessary to use the two casting bodies obtained by pouring as intermediate pieces, and use the intermediate piece as a mold to perform a similar pouring to obtain the artificial experimental samples required for the experiment. .
(2)间接浇筑方法。间接浇筑方法是对直接浇筑方法的改进。不同于直接浇筑方法需要先制作中间件，间接浇筑方法先使用硅胶或者树脂等材料对裂缝面进行翻模。在翻模前无需对天然裂缝岩样进行切割，而是将翻模得到的硅胶树脂等材料切割成规则外形后进行浇筑来得到人造实验样品。(2) Indirect pouring method. The indirect pouring method is an improvement over the direct pouring method. Different from the direct pouring method, which needs to make intermediate parts first, the indirect pouring method first uses materials such as silica gel or resin to mold the cracked surface. There is no need to cut the natural fractured rock samples before turning over the mold, but the silicone resin and other materials obtained by turning over the mold are cut into regular shapes and poured to obtain artificial experimental samples.
(3)基于裂缝表面轮廓线测量的制作方法(发明专利申请号20141083577.0)。该方法首先利用三维(3D)激光扫描方法对5到10米的大尺寸裂缝面的表面轮廓线和倾向、倾角、走向进行测量。在对测量数据进行诸如去噪，缩放等处理后，得到了小尺寸的裂缝面模型。将其导入电火花切割控制机加工出带有相应轮廓线形状和倾向、倾角、走向的钢块便可浇筑出人造实验样品。该方法被用于研究裂缝充填物物理性质对裂缝岩体的强度和变形特性的影响。(3) A fabrication method based on crack surface contour measurement (invention patent application number 20141083577.0). The method first uses a three-dimensional (3D) laser scanning method to measure the surface contour, inclination, dip angle, and strike of a large-scale fracture surface of 5 to 10 meters. After processing the measurement data such as denoising and scaling, a small-scale fracture surface model is obtained. Import it into the electric discharge cutting control machine to process steel blocks with corresponding contour lines, inclinations, inclinations, and directions, and then pour artificial experimental samples. This method is used to study the effect of the physical properties of fracture fillings on the strength and deformation characteristics of fractured rock mass.
对于直接浇筑方法，其缺点是制作过程中需对天然裂缝岩样进行切割和翻动，有可能会对裂缝面造成破坏。同时需要额外的一次翻模，这使得浇筑材料消耗较多，制作成本较高。而每次翻模倒模的候凝成型时间都在1天左右，制作周期也较长。而间接浇筑方法无需切割天然裂缝岩样也较省浇筑材料，但受硅胶和树脂等材料自身流动能力的影响，可能在翻模时由于天然裂缝岩样裂缝表面上的气泡难以排除而不能完整地拓印裂缝形貌。同时由于硅胶材质较软易破损，在浇筑时不能使用钢丝等硬物进行振捣来排除气泡。这都将造成人造实验样品的裂缝形貌与天然裂缝岩样存在差异。另外需要特别指出的是，由于对深部地层的钻井取芯成本很高，通常需要充分利用每一块岩心来进行各种实验，如渗透率、孔隙度的测量，岩心的计算机断层扫面重建等。而直接使用水泥砂浆进行翻模的过程中的液相可能会渗入天然裂缝岩样内部而造成污染，硅胶和树脂翻模也可能会污染天然裂缝岩样表面。这将导致天然裂缝岩样不能再进行其他实验，无疑进一步提高了人造实验样品的制作成本。而基于裂缝面测量的制作方法则很好的避免了这些问题，在整个制作过程中由于采用了激光进行非接触式的原位测量，并不会对天然裂缝岩样产生污染。但其针对5到10米的大尺寸裂缝面，仅测量裂缝面的表面轮廓线和倾向、倾角、走向，而忽略了裂缝面的具体形貌。因而由此获得的人造实验样品也仅包含了裂缝面的表面轮廓线和倾向、倾角、走向信息，忽略了裂缝面的具体形貌细节。如果直接使用由其制作的人造实验样品来进行研究将不能很好地反映裂缝表面的具体形貌对岩体性质的影响。同时基于裂缝面测量的制作方法采用电火花切割加工钢块的方式制作浇筑模具，其加工时间和加工成本也较高。For the direct pouring method, its disadvantage is that the natural fracture rock samples need to be cut and turned during the fabrication process, which may cause damage to the fracture surface. At the same time, an additional overturning is required, which leads to more consumption of pouring materials and higher production costs. However, the waiting and solidification time for each mold turning and inversion is about 1 day, and the production cycle is also relatively long. The indirect pouring method does not need to cut the natural fracture rock sample and saves pouring materials. However, due to the influence of the flow ability of materials such as silica gel and resin, it may not be possible to completely remove the air bubbles on the crack surface of the natural fracture rock sample when turning over the mold. The morphology of rubbing cracks. At the same time, because the silicone material is soft and easy to break, hard objects such as steel wires cannot be used to vibrate to remove air bubbles during pouring. All these will cause the fracture morphology of artificial experimental samples to be different from natural fracture rock samples. In addition, it should be pointed out that due to the high cost of drilling and coring deep formations, it is usually necessary to make full use of each core to conduct various experiments, such as the measurement of permeability and porosity, and the reconstruction of computer tomography of cores. However, the liquid phase in the process of directly using cement mortar for molding may penetrate into the interior of natural fractured rock samples and cause pollution, and silica gel and resin molding may also pollute the surface of natural fractured rock samples. This will lead to the failure of other experiments on natural fractured rock samples, which will undoubtedly further increase the production cost of artificial experimental samples. The fabrication method based on fracture surface measurement avoids these problems very well. During the entire fabrication process, the laser is used for non-contact in-situ measurement, which will not pollute the natural fracture rock samples. However, for large-scale fracture surfaces of 5 to 10 meters, it only measures the surface contour, inclination, inclination, and strike of the fracture surface, while ignoring the specific shape of the fracture surface. Therefore, the artificial experimental samples obtained from this only include the surface contour of the fracture surface and information on the inclination, inclination, and direction of the fracture surface, ignoring the specific morphology details of the fracture surface. If the artificial experimental samples made by it are directly used for research, it will not be able to reflect the influence of the specific morphology of the fracture surface on the properties of the rock mass. At the same time, the manufacturing method based on crack surface measurement adopts the method of electric discharge cutting to process the steel block to manufacture the pouring mold, and its processing time and processing cost are also relatively high.
而采用目前较为成熟的3D扫描技术和3D打印技术，可以非接触式地、快速、精确而又完整地获取整个裂缝面形貌的几何数据。在对扫描数据进行处理后便可采用3D打印技术快速、成批量地制作出浇筑用的模具来浇筑人造实验样品。这样便能达到高品质、低成本、快速地制作人造实验样品的目的。However, using the currently more mature 3D scanning technology and 3D printing technology, the geometric data of the entire fracture surface can be obtained in a non-contact, fast, accurate and complete manner. After processing the scanned data, 3D printing technology can be used to quickly and batch-produce pouring molds to pour artificial experimental samples. In this way, the purpose of high-quality, low-cost, and rapid production of artificial experimental samples can be achieved.
发明内容Contents of the invention
本发明的目的是克服现有的裂缝岩体研究中人造实验样品的制备方法会对作为仿制对象的天然裂缝岩样造成破坏和污染，且制作成本较高，制作周期较长的不足，提出的一种仿制天然裂缝岩样的人造实验样品制作方法。该方法采用3D扫描技术对天然裂缝岩样的完整裂缝形貌几何参数进行精确测量，扫描数据经过软件处理后采用3D打印技术快速批量制造浇筑模具以缩短人造实验样品的制作周期。The purpose of the present invention is to overcome the shortcomings that the artificial experimental sample preparation method in the existing cracked rock mass research will cause damage and pollution to the natural cracked rock sample as the imitation object, and the production cost is high and the production cycle is long. A method for making artificial experimental samples imitating natural fractured rock samples. This method uses 3D scanning technology to accurately measure the geometric parameters of the complete fracture shape of natural fractured rock samples. After the scanning data is processed by software, 3D printing technology is used to quickly and batch-manufacture pouring molds to shorten the production cycle of artificial experimental samples.
为实现上述目的，本发明是通过以下技术方案实现的：To achieve the above object, the present invention is achieved through the following technical solutions:
一种仿制天然裂缝岩样的人造实验样品制作方法，包括如下步骤：A method for making an artificial experimental sample imitating a natural fractured rock sample, comprising the steps of:
(1)测量天然裂缝岩样的裂缝面的大致尺寸，并根据实验要求和3D打印机的最大打印尺寸共同确定用于制作浇筑模具和人造实验样品的裂缝面的长度和宽度。(1) Measure the approximate size of the fracture surface of the natural fracture rock sample, and determine the length and width of the fracture surface used to make the pouring mold and artificial experimental samples according to the experimental requirements and the maximum printing size of the 3D printer.
(2)按照上一步确定的裂缝面的长度和宽度，选定3D扫描仪的单次扫描区域大小并对3D扫描仪进行校准。然后使用3D扫描仪对天然裂缝岩样的裂缝面形貌几何参数进行精确测量，通过一次扫描或多次扫描后拼接获取完整裂缝形貌的点云数据。(2) According to the length and width of the fracture surface determined in the previous step, select the single scanning area size of the 3D scanner and calibrate the 3D scanner. Then use a 3D scanner to accurately measure the geometric parameters of the fracture surface of the natural fractured rock sample, and obtain the point cloud data of the complete fracture morphology by splicing after one scan or multiple scans.
(3)在与3D扫描仪配套的操作软件中进行“点云数据全局优化”和“去除重叠点云”操作并保存。(3) Perform the operations of "global optimization of point cloud data" and "removal of overlapping point clouds" in the operating software matched with the 3D scanner and save them.
(4)将经过上一步处理的点云导出保存，然后导入GeomaticStudio逆向工程软件中。由于实验通常使用一个面为裂缝面的长方体人造实验样品，因此在GeomaticStudio中按照实验所需的裂缝面尺寸裁剪掉多余的点云，然后将点云封装成三角形面片以STL文件格式保存。此时便得到一个边界为长方形的裂缝面。(4) Export and save the point cloud processed in the previous step, and then import it into GeomaticStudio reverse engineering software. Since the experiment usually uses a cuboid artificial experimental sample whose surface is a crack surface, the redundant point cloud is cut out according to the size of the crack surface required for the experiment in GeomaticStudio, and then the point cloud is packaged into a triangular patch and saved in STL file format. At this time, a fracture surface with a rectangular boundary is obtained.
(5)将上一步获得的STL模型文件导入Pro/Engineer建模软件中，在裂缝面的四周补充平面，在裂缝面的底部也补充一个平面。这使得整个模型封闭，成为有一个面为裂缝面的长方体，也就是用于浇筑的裂缝面模具的计算机三维模型。将做好的裂缝面模具的计算机三维模型以STL文件格式保存。(5) Import the STL model file obtained in the previous step into Pro/Engineer modeling software, add planes around the crack surface, and add a plane at the bottom of the crack surface. This makes the whole model closed as a cuboid with one face as the crack face, which is the computerized 3D model of the crack face mold for pouring. Save the completed computer 3D model of the fracture surface mold in STL file format.
(6)将裂缝面模具的计算机三维模型导入3D打印机配套的切片软件，生成切片文件并导入3D打印机将裂缝面模具打印出来。视裂缝面模具的大小，一台3D打印机可同时打印一个或多个裂缝面模具，还可以在浇筑候凝的过程中同时打印裂缝面模具，能够缩短总的人造实验样品制作时间。(6) Import the computer 3D model of the crack surface mold into the slicing software supporting the 3D printer, generate a slice file and import it into the 3D printer to print out the crack surface mold. Depending on the size of the crack surface mold, a 3D printer can print one or more crack surface molds at the same time, and can also print the crack surface molds at the same time during the pouring process, which can shorten the total artificial experimental sample production time.
(7)为进行浇筑还需要4块尺寸与裂缝面模具边长相匹配的平板来围成浇筑盒。为方便脱模，采用分体式设计将浇筑盒沿其对角线分成2个分开的对称模型在三维建模软件中进行建模并保存为STL文件格式，然后同样采用3D打印技术制作出来。(7) For pouring, 4 flat plates whose size matches the side length of the mold on the crack surface are required to form a pouring box. In order to facilitate the demoulding, the pouring box is divided into two separate symmetrical models along its diagonal by adopting split design, which are modeled in 3D modeling software and saved as STL file format, and then produced by 3D printing technology as well.
(8)在制作完浇筑盒后，将裂缝面模具放入浇筑盒底部。随后对浇筑盒进行加固，可在浇筑盒外用铁丝进行缠绕捆绑加固，也可用重物抵住浇筑盒，从而防止出现浇筑盒上有较大的缝隙以及浇筑材料定型前浇筑盒变形而导致的浇筑失败。浇筑模具由浇筑盒与裂缝面模具一起组成。(8) After making the pouring box, put the crack surface mold into the bottom of the pouring box. Then strengthen the pouring box, which can be wrapped and bound with iron wire outside the pouring box, or heavy objects can be used to hold the pouring box, so as to prevent large gaps on the pouring box and pouring caused by the deformation of the pouring box before the pouring material is finalized fail. The pouring mold consists of a pouring box together with a fracture face mold.
(9)配置浇筑材料。实际上目前能模拟岩石性能的浇筑材料有很多种，如水泥砂浆、灌浆料、混凝土、石膏等。即使是同一类材料，不同学者也采用了不同的配比。以水泥砂浆为例，河沙与水泥之比常在1～5之间浮动，水泥含量越高则浇筑成的水泥砂浆的强度也越高。此外还会向浇筑材料中添加一定量的外加剂来改变其的性能。比如加入早强剂使得浇筑材料在短期内获得较高的强度以早日脱模，加快模具的中转。还比如加入消泡剂和膨胀剂提高浇筑材料的成型品质。总的来说通常都需进行不同配比的浇筑实验来确定浇筑材料的力学性能是否达到预期目标。(9) Configure pouring materials. In fact, there are many kinds of pouring materials that can simulate the performance of rocks, such as cement mortar, grouting material, concrete, gypsum, etc. Even for the same type of material, different scholars have adopted different ratios. Taking cement mortar as an example, the ratio of river sand to cement often fluctuates between 1 and 5. The higher the cement content, the higher the strength of the poured cement mortar. In addition, a certain amount of admixture will be added to the pouring material to change its performance. For example, adding an early strength agent can make the pouring material obtain higher strength in a short period of time to release the mold early and speed up the transfer of the mold. Another example is adding defoamers and expansion agents to improve the molding quality of pouring materials. In general, it is usually necessary to conduct pouring experiments with different proportions to determine whether the mechanical properties of the pouring materials meet the expected goals.
本发明提出了一种仿制天然裂缝岩样的人造实验样品制作方法，使用浇筑材料在3D打印机制作的浇筑盒和裂缝面模具中进行浇筑成型是制作人造实验样品的核心步骤。但由于浇筑材料配方多种多样，选择余地很大。因此浇筑材料的具体配方不做为本发明的权利要求内容，技术方案中也不详细说明，仅在具体实施方式中介绍一种配方。The present invention proposes a method for making artificial experimental samples imitating natural cracked rock samples. The core step of making artificial experimental samples is to use pouring materials to pour and form them in pouring boxes and crack surface molds made by 3D printers. However, due to the variety of pouring material formulas, there is a lot of room for choice. Therefore, the specific formula of the pouring material is not regarded as the content of the claims of the present invention, nor is it described in detail in the technical solution, and only one formula is introduced in the specific implementation.
(10)在配置好浇筑材料后，在浇筑盒内壁和裂缝面模具表面上刷一层脱模剂以帮助后面脱模。随后将浇筑材料迅速倒入浇筑盒中，并使用钢丝等硬物振捣直到表面不在有气泡出现。然后用刮刀刮平浇筑试样的表面，并清理掉从浇筑盒缝隙中渗出来的浇筑材料。在室待恒温恒湿的条件下养护24小时后脱模编号备用。(10) After configuring the pouring materials, brush a layer of release agent on the inner wall of the pouring box and the mold surface on the crack surface to help the demoulding later. Then quickly pour the pouring material into the pouring box, and vibrate with hard objects such as steel wire until there are no air bubbles on the surface. Then scrape the surface of the pouring sample with a scraper, and clean up the pouring material seeping from the gap of the pouring box. After curing for 24 hours under the condition of constant temperature and humidity in the room, the demoulding numbers are ready for use.
(11)视实验所需要的人造实验样品数量和已有的裂缝面模具数量，可使用脱模后的模具在清洗风干后继续进行浇筑。若实验所需要的人造实验样品数量远大于已有的浇筑模具数量，可在浇筑候凝的同时继续使用3D打印技术制作浇筑模具。同时考虑到已浇筑的样品中可能存在一些瑕疵品，可适当多做一些样品备用。在所需数量的人造实验样品制备完成后，检查其表面是否有明显的缺陷，如大的裂纹和气泡以及表面不平整。剔除掉这些有缺陷的的样品后，如果剩余样品数量少于实验所需要的人造实验样品数量则重复步骤(10)，否则人造实验样品制作过程结束。在人造实验样品制作过程结束后，对浇筑模具进行清洗并放于室内自然风干，随后清点模具并观察其表面是否存在破损。保留没有破损的模具以供下次使用，同时对每次浇筑所使用的裂缝面模具和浇筑盒的STL模型文件进行归档保存。(11) Depending on the number of artificial experimental samples required for the experiment and the number of existing crack surface molds, the demoulded mold can be used to continue pouring after cleaning and air drying. If the number of artificial experimental samples required for the experiment is much greater than the number of existing pouring molds, 3D printing technology can be used to make pouring molds while pouring and waiting. At the same time, considering that there may be some defective products in the poured samples, some more samples can be made appropriately for backup. After the required number of artificial experimental samples have been prepared, check their surface for obvious defects such as large cracks and air bubbles and surface unevenness. After removing these defective samples, if the number of remaining samples is less than the number of artificial experimental samples required for the experiment, then repeat step (10), otherwise the process of making artificial experimental samples ends. After the artificial experimental sample production process was completed, the pouring mold was cleaned and placed in the room to dry naturally, and then the mold was checked to see if there was any damage on the surface. Keep undamaged molds for next use, and at the same time archive and save the STL model files of crack surface molds and pouring boxes used for each pouring.
与现有的浇筑制备人造实验样品的方法相比，本发明具有以下有益效果：Compared with the existing pouring method for preparing artificial experimental samples, the present invention has the following beneficial effects:
(1)通过对天然裂缝岩样的裂缝面进行3D扫描，可以非接触式地、快速而又完整地获取整个裂缝面形貌的几何数据，并基于由此获得的扫描数据采用3D打印机制作裂缝面模具，制作出的裂缝面模具真实地反映了裂缝面的形貌特征。同时3D打印机制作的浇筑模具使用聚乳酸(PLA)材料，成型后的收缩率较低，即使制作较大尺寸的浇筑模具也表现良好。此外成型后的浇筑模具表面光洁，硬度较高，在浇筑成型的过程中可以用钢丝等硬物振捣排除气泡。这样便提高了人造实验样品的成型品质。(1) Through 3D scanning of the fracture surface of natural fracture rock samples, the geometric data of the entire fracture surface morphology can be obtained non-contact, quickly and completely, and based on the obtained scanning data, 3D printers are used to make fractures Surface mold, the produced crack surface mold truly reflects the morphology of the crack surface. At the same time, the pouring mold made by the 3D printer uses polylactic acid (PLA) material, which has a low shrinkage rate after molding, and performs well even if the pouring mold of a larger size is made. In addition, the molded pouring mold has a smooth surface and high hardness, and hard objects such as steel wires can be used to vibrate to remove air bubbles during the pouring and molding process. This improves the molding quality of artificial experimental samples.
(2)由于采用了3D扫描技术和3D打印技术制作浇筑模具，在整个过程中天然裂缝岩样不会受到污染和破坏，3D扫描完成后就能够直接拿去做其他实验测试。同时浇筑材料仅用于人造实验样品的制作，无需额外浇筑中间件。此外采用3D打印技术所使用的材料价格便宜，每次制作浇筑模具的消耗也较少，因此还具有模具制作成本低廉这一特点。这样便降低了人造实验样品的制作成本。(2) Due to the use of 3D scanning technology and 3D printing technology to make casting molds, natural fracture rock samples will not be polluted and damaged during the whole process, and can be directly used for other experimental tests after 3D scanning is completed. At the same time, the pouring material is only used for the production of artificial experimental samples, without additional pouring intermediates. In addition, the materials used by 3D printing technology are cheap, and the consumption of casting molds is less each time, so it also has the characteristics of low mold production costs. This reduces the production cost of artificial experimental samples.
(3)采用3D打印技术能够快速批量地制作浇筑模具，在浇筑候凝的同时能继续制作更多的浇筑模具。这样便降低了人造实验样品的制作周期。(3) The use of 3D printing technology can quickly and batch-produce pouring molds, and can continue to make more pouring molds while pouring and waiting. This reduces the production cycle of artificial experimental samples.
(4)由于每次浇筑所使用的裂缝面模具和浇筑盒的STL模型文件都要进行归档保存，即使天然裂缝岩样本身以及前期制作的裂缝面模具实物和浇筑盒实物均已被破坏，也能随时利用归档保存的STL模型文件来加工人造实验样品，具有可重复性。(4) Since the STL model files of the fracture surface mold and pouring box used for each pouring have to be archived and preserved, even if the natural fracture rock sample itself and the crack surface mold and pouring box produced in the previous stage have been destroyed, it is impossible to The archived and saved STL model files can be used at any time to process artificial experimental samples, which is repeatable.

具体实施方式Detailed ways
下面结合具体实施方式对本发明最进一步详细描述：Below in conjunction with specific embodiment the present invention is described in further detail:
本发明的人造实验样品制造方法的流程如图1所示，包括天然裂缝岩样估测、3D扫描、浇筑模具建模、3D打印、浇筑成型这5个步骤。下面用实施例对这5个步骤进行说明。The process flow of the artificial experimental sample manufacturing method of the present invention is shown in Figure 1, including five steps of natural fracture rock sample estimation, 3D scanning, pouring mold modeling, 3D printing, and pouring molding. These 5 steps are described below with examples.
(1)针对图2所示的天然裂缝岩样，估测其长度为172毫米，宽度为105毫米。本实施例中所采用的如图3所示的FDM35-2525型3D打印机能制作最大长度和宽度都为250毫米，最大高度为350毫米的浇筑模具，天然裂缝岩样的尺寸在3D打印机允许制作的范围内。本实施例中实验所需要制作的人造实验样品长度和宽度均为50毫米，高度要求在50毫米左右。因此只需获取天然裂缝岩样的部分裂缝面数据。由于采用3D扫描技术，因此无需对天然裂缝岩样进行切割加工即可获取裂缝表面形貌数据。(1) For the natural fracture rock sample shown in Figure 2, it is estimated that its length is 172 mm and its width is 105 mm. The FDM35-2525 type 3D printer that adopts in the present embodiment as shown in Figure 3 can make maximum length and width all be 250 millimeters, maximum height is the pouring mold of 350 millimeters, and the size of natural crack rock sample is allowed to make in 3D printer In the range. The length and width of the artificial experimental samples required for the experiment in this embodiment are both 50 mm, and the height is required to be about 50 mm. Therefore, it is only necessary to obtain partial fracture surface data of natural fractured rock samples. Due to the use of 3D scanning technology, fracture surface morphology data can be obtained without cutting and processing natural fracture rock samples.
(2)根据上一步选定的所需裂缝面尺寸，选定如图4所示的EaScan-D抄数测绘3D扫描仪的单次扫描区域的长度为100毫米，宽度为75毫米。照3D扫描仪厂家提供的校正板和校正步骤进行校正。此时3D扫描仪的测量误差是0.015毫米，扫描获得的点云的间距是0.08毫米，可以精确获取裂缝面形貌的几何参数。将扫描模式选为特征扫描，这样便可从多个角度充分获取裂缝面的形貌数据，最后拼接成一个包含完整裂缝面形貌数据的点云。从不同的角度大概扫描6～10次后，观察拼接成的点云是否存在空白区域，即仍未扫描到的地方。若有破洞则针对该区域进行多次更细致的扫描以补充数据。最后获得如图5所示的裂缝面形貌点云，在3D扫描仪配套的操作软件中进行“点云数据全局优化”和“去除重叠点云”操作并保存。(2) According to the required fracture surface size selected in the previous step, the length of the single scanning area of the EaScan-D digital surveying and mapping 3D scanner shown in Figure 4 is selected to be 100 mm and the width is 75 mm. Calibrate according to the calibration plate and calibration steps provided by the 3D scanner manufacturer. At this time, the measurement error of the 3D scanner is 0.015 mm, and the distance between the point clouds obtained by scanning is 0.08 mm, which can accurately obtain the geometric parameters of the fracture surface morphology. The scanning mode is selected as feature scanning, so that the topography data of the fracture surface can be fully obtained from multiple angles, and finally spliced into a point cloud containing the complete topography data of the fracture surface. After scanning about 6 to 10 times from different angles, observe whether there is a blank area in the spliced point cloud, that is, a place that has not been scanned yet. If there is a hole, multiple more detailed scans of the area are taken to supplement the data. Finally, the point cloud of fracture surface morphology as shown in Figure 5 was obtained, and the operations of "global optimization of point cloud data" and "removal of overlapping point cloud" were performed in the operating software of the 3D scanner and saved.
(3)将上一步获得的点云数据导入GeomaticStudio逆向工程软件中，使用“矩形选择工具”在裂缝面点云上选取一个边长为50毫米的正方形区域，然后进行“反转选择”操作选中除该正方形区域外的其他点云并删除，即获得了实验所需尺寸的裂缝面点云数据。对其进行“封装”操作将点云转化为三角形面片并以STL文件格式保存。将刚刚保存的文件导入到Pro/Engineer建模软件中，在裂缝面的四周补齐平面，在裂缝面的底部也补充一个平面，获得如图6中所示的计算机三维模型并以STL文件格式保存。根据实验要求，在Pro/Engineer中为浇筑盒进行三维建模。为了方便脱模，浇筑盒采用分体式设计由两部分组成，其外形如图7所示。浇筑盒A7-1和浇筑盒B7-2的内部尺寸与裂缝面模具7-3相匹配，而外部尺寸稍大。本实施例中浇筑盒的内边长为50毫米，外边长为70毫米，厚度为10毫米，高度为50毫米。这样设计的浇筑盒结构简单且脱模方便，同时也有足够的硬度来保证成型。完成浇筑盒的建模后，将模型保存为STL文件格式。(3) Import the point cloud data obtained in the previous step into GeomaticStudio reverse engineering software, use the "rectangular selection tool" to select a square area with a side length of 50 mm on the fracture surface point cloud, and then perform the "reverse selection" operation to select The other point clouds except the square area are deleted, and the fracture surface point cloud data of the size required for the experiment is obtained. The "encapsulation" operation is performed on it to convert the point cloud into a triangular patch and save it in the STL file format. Import the file just saved into the Pro/Engineer modeling software, fill in the plane around the crack surface, and add a plane at the bottom of the crack surface, and obtain the computer 3D model as shown in Figure 6 and save it in STL file format save. According to the requirements of the experiment, 3D modeling was carried out for the pouring box in Pro/Engineer. In order to facilitate demoulding, the pouring box adopts a split design and consists of two parts, and its appearance is shown in Figure 7. The inner dimensions of the pouring box A7-1 and the pouring box B7-2 match the crack face mold 7-3, while the outer dimensions are slightly larger. In this embodiment, the inner side length of the pouring box is 50 mm, the outer side length is 70 mm, the thickness is 10 mm, and the height is 50 mm. The pouring box designed in this way is simple in structure and easy to demould, and also has sufficient hardness to ensure molding. After finishing modeling the pouring box, save the model as an STL file format.
在本实施例中以上3个步骤总共耗时42分钟。In this embodiment, the above 3 steps took a total of 42 minutes.
(4)将裂缝面模具模型和浇筑盒模型的STL模型文件导入与3D打印机配套的切片软件中进行切片，获得指导3D打印机工作的切片文件。将切片文件存入SD卡，再将SD卡插入3D打印机中并让其加载切片文件打印出裂缝面模具模型和浇筑盒的实物。本实施例中每组裂缝面模具和浇筑盒的制作时间为3小时35分钟，消耗3D打印机材料60克。制作速度受本实施例中所使用的3D打印机性能限制，若使用新型的KosselDelta型3D打印机制作速度还可以提高2到3倍。浇筑模具打印数量根据实验所需的人造实验样品数量决定。若实验所需的人造实验样品数量较多，可采取模具制作和浇筑同时进行的策略，在一定时间后即可获得较高的人造实验样品产出量。最终获得如图8所示的裂缝面模具和浇筑盒。(4) Import the STL model files of the mold model of the fracture surface and the pouring box model into the slicing software matched with the 3D printer for slicing, and obtain the slicing files that guide the work of the 3D printer. Store the slicing file into the SD card, then insert the SD card into the 3D printer and let it load the slicing file to print out the mold model of the fracture surface and the real object of the pouring box. In this embodiment, the production time of each group of fracture surface molds and pouring boxes is 3 hours and 35 minutes, and consumes 60 grams of 3D printer materials. The production speed is limited by the performance of the 3D printer used in this embodiment, if the new KosselDelta type 3D printer is used, the production speed can be increased by 2 to 3 times. The number of casting molds to be printed is determined according to the number of artificial experimental samples required for the experiment. If the number of artificial experimental samples required for the experiment is large, the strategy of simultaneous mold making and pouring can be adopted, and a higher output of artificial experimental samples can be obtained after a certain period of time. Finally, the fracture surface mold and casting box as shown in Fig. 8 are obtained.
(5)将裂缝面模具放在坚硬平坦的地面上，将浇筑盒按照图8中左侧和图9所示的组合方式与裂缝面模具装配起来。用铁丝在浇筑盒外壁面上缠紧，并紧贴浇筑盒外壁面堆放重物以对浇筑盒进行加固。按照水：水泥：河沙＝1：2：4的质量配比配置水泥砂浆作为浇筑材料。将浇筑材料搅拌均匀后倒入浇筑盒内，随后用钢丝等硬物进行振捣和对浇筑内壁面进行刮擦，从而使得气泡得出排除。待水泥砂浆表面没有气泡溢出后，刮去表面多余的水泥砂浆，清理掉地面上和从浇筑盒边缘渗出的水泥砂浆。在室内保存恒温恒湿的条件下养护24小时后脱模编号备用。检查是否存在残缺品，如含有大的裂纹、气泡等。在人造实验样品制作过程结束后，将浇筑模具拆开进行清洗并放于室内自然风干，随后清点裂缝面模具和浇筑盒并观察其表面是否存在破损。保留没有破损的裂缝面模具和浇筑盒以供下次使用，同时对本次浇筑所使用的裂缝面模具和浇筑盒的STL模型文件进行归档保存。(5) Put the crack surface mold on a hard and flat ground, and assemble the pouring box with the crack surface mold according to the combination shown on the left side of Figure 8 and Figure 9. Tighten the outer wall of the pouring box with iron wire, and stack heavy objects close to the outer wall of the pouring box to reinforce the pouring box. According to the mass ratio of water: cement: river sand = 1:2:4, cement mortar is used as the pouring material. Stir the pouring material evenly and pour it into the pouring box, then vibrate with hard objects such as steel wire and scrape the inner wall surface of the pouring, so that the air bubbles can be removed. After there are no air bubbles overflowing from the surface of the cement mortar, scrape off the excess cement mortar on the surface, and clean up the cement mortar on the ground and seeping from the edge of the pouring box. Stored indoors under constant temperature and humidity conditions for 24 hours after curing, the demoulding number is ready for use. Check for defective products, such as large cracks, air bubbles, etc. After the artificial experimental sample production process was completed, the pouring mold was disassembled for cleaning and air-dried indoors, and then the cracked surface mold and pouring box were checked to see if there was any damage on the surface. Keep undamaged crack surface molds and pouring boxes for next use, and at the same time archive and save the STL model files of the crack surface molds and pouring boxes used in this pouring.
最终获得的人造实验样品如图10所示。观察图10发现人造实验样品表面存在一些裂纹。这是因为本实施例中所配置的水泥砂浆没有加入膨胀剂和消泡剂等外加剂，在其凝固过程中体积会不断缩小导致裂纹的产生。这可以通过改良水、水泥、河沙的配比，以及加入适量的外加剂来避免，并非是本发明所提出的制作方法的自身缺陷。The finally obtained artificial experimental sample is shown in Figure 10. Observing Figure 10, it is found that there are some cracks on the surface of the artificial experimental sample. This is because the cement mortar configured in this embodiment does not add additives such as expansion agent and defoamer, and the volume will continuously shrink during its solidification process, resulting in cracks. This can be avoided by improving the proportioning of water, cement and river sand, and adding an appropriate amount of admixture, and it is not the inherent defect of the production method proposed by the present invention.
上述仅本发明较佳可行的实施例，非因此局限本发明保护范围，依照上述实施例所作各种变形或套用均在此技术方案保护范围之内。The above are only preferred and feasible embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Various modifications or applications made according to the above embodiments are within the protection scope of this technical solution.
