Description

一种掺砾料大三轴试验电渗固结法An Electroosmotic Consolidation Method for Large Triaxial Test of Gravel Mixed Materials

技术领域technical field

本发明涉及一种大三轴试验的固结方法,特别涉及一种掺砾料大三轴试验电渗固结法。The invention relates to a consolidation method for a large triaxial test, in particular to an electroosmotic consolidation method for a large triaxial test with gravel.

背景技术Background technique

我国西南地区在建和待建的高心墙堆石坝很多,很多坝体高度达到200m以上,甚至达到了300m级。传统的采用粘性土心墙作为防渗体的做法已不能满足超高土石坝心墙强度和变形的要求。砾质土经碾压后一般可获得较高的密度及强度、较低的压缩性以及较好的防渗性能,这种掺砾料已在高土石坝工程中被广泛地用作心墙防渗材料。There are many high-core rockfill dams under construction or to be built in Southwest my country, and the height of many dams reaches more than 200m, or even 300m. The traditional method of using cohesive soil core wall as anti-seepage body can no longer meet the strength and deformation requirements of super-high earth-rockfill dam core wall. After rolling, gravel soil can generally obtain higher density and strength, lower compressibility and better anti-seepage performance. This kind of gravel mixed material has been widely used as core wall anti-seepage in high earth-rock dam engineering seepage material.

在高心墙坝设计计算中,必须了解掺砾心墙料的强度变形特性,因此需要开展三轴试验。由于掺砾料具有较大的粒径,不能开展常规尺寸的三轴试验,因此需要进行大三轴试验,试样直径一般为300mm×600mm。在掺砾心墙料的大三轴强度变形试验中,试样首先需要固结。In the design and calculation of high core wall dams, it is necessary to understand the strength and deformation characteristics of gravel core wall materials, so triaxial tests are required. Due to the large particle size of the gravel material, a triaxial test of a conventional size cannot be carried out, so a large triaxial test is required, and the sample diameter is generally 300mm×600mm. In the large triaxial strength-deformation test of gravel-mixed core wall materials, the specimen first needs to be consolidated.

在本发明之前,试样固结都采用在围压作用下固结的方法。由于试样直径大(300mm),排水路径较长,因此固结时间非常长。固结时间与掺砾量的多少有关,掺砾越少,则固结时间越长。例如,一个掺砾50%的试样,固结时间需要一个星期左右。如果掺砾量更少时,固结时间将长达几个星期。试样固结期间,占用了试验仪器,浪费了宝贵的试验资源。一个土石坝往往需要进行数十组大三轴试验,若按照这个固结时间计算,所需的试验周期将非常长,浪费时间,试验效率低。Before the present invention, the method of consolidating under the action of confining pressure was adopted for the consolidation of samples. Due to the large diameter of the specimen (300mm) and the long drainage path, the consolidation time was very long. The consolidation time is related to the amount of gravel mixed, the less gravel mixed, the longer the consolidation time. For example, for a sample mixed with 50% gravel, the consolidation time takes about one week. If the amount of gravel is less, the consolidation time will be as long as several weeks. During the consolidation of the sample, the test equipment is occupied and precious test resources are wasted. Dozens of large triaxial tests are often required for an earth-rock dam. If calculated according to this consolidation time, the required test period will be very long, which is a waste of time and low test efficiency.

发明内容Contents of the invention

本发明的目的就在于克服上述大三轴试验试样固结时间长、试验效率低的缺陷,提出一种掺砾料大三轴试验的电渗固结方法。The purpose of the present invention is to overcome the defects of long consolidation time and low test efficiency of the above-mentioned large triaxial test sample, and propose an electroosmotic consolidation method for large triaxial test of gravel material.

本发明的技术方案是:Technical scheme of the present invention is:

一种掺砾料大三轴试验的电渗固结方法,包括以下步骤:A kind of electroosmotic consolidation method of large triaxial test of gravel material, comprising the following steps:

(1)在大型三轴仪底座和盖板上预留排水孔道和导线穿越孔道;(1) Reserve drain holes and wire passing holes on the base and cover of the large triaxial instrument;

(2)在底座上依次放置绝缘板、电极板和滤纸;(2) Place the insulating plate, the electrode plate and the filter paper in sequence on the base;

(3)将下部的导线穿过底座和绝缘板,与下部电极板连接;(3) Pass the lower wire through the base and the insulating plate, and connect with the lower electrode plate;

(4)在底座上制作掺砾料试样;(4) Make a gravel-mixed sample on the base;

(5)在试样上依次放置滤纸、电极板和绝缘板;(5) Place filter paper, electrode plate and insulating plate in sequence on the sample;

(6)将上部的导线穿过盖板和绝缘板,与上部电极板连接;(6) Pass the upper wire through the cover plate and the insulating plate, and connect with the upper electrode plate;

(7)接通排水管;(7) Connect the drain pipe;

(8)将上、下两根导线从压力室引出,并与外部电源连接;(8) Lead the upper and lower wires out of the pressure chamber and connect them to the external power supply;

(9)接通电源,试样发生电渗固结。(9) Turn on the power, and the sample undergoes electroosmotic consolidation.

在步骤(2)和(6)中,所述的电极板采用电动土工合成材料(简称EGK)制作。电动土工合成材料内部已被织入导电材料,如石墨、金属丝等,可以导电,又有很多上下贯通的针状小孔,方便排水。所述电极板直径与试样相同;绝缘板采用绝缘的硬塑料制作而成,直径与电极板直径相同,且在绝缘板上预留导线孔洞。In steps (2) and (6), the electrode plate is made of electrodynamic geosynthetics (EGK for short). Electric geosynthetics have been woven into conductive materials, such as graphite, metal wire, etc., which can conduct electricity, and there are many needle-like holes that penetrate up and down to facilitate drainage. The diameter of the electrode plate is the same as that of the sample; the insulating plate is made of insulating hard plastic, the diameter is the same as that of the electrode plate, and holes for wires are reserved on the insulating plate.

本发明方法还可以在步骤(9)电渗固结过程中进行电极转换。The method of the present invention can also perform electrode switching during the electroosmotic consolidation process in step (9).

本发明的方法在电渗固结的同时,试样可加上围压,使试样在围压-电渗联合作用下发生固结。In the method of the invention, confining pressure can be added to the sample while electroosmosis is being consolidated, so that the sample is consolidated under the joint action of confining pressure and electroosmosis.

本发明的优点和效果在于:Advantage and effect of the present invention are:

采用电渗法进行掺砾料大三轴试验试样的固结,克服了传统固结方法由于试样尺寸大、排水路径长导致试样固结慢的缺点,使采用常规围压固结所需时间从数天乃至数星期变成了几个小时,大大缩短了固结时间,提高了工作效率。The electroosmotic method is used to consolidate the large triaxial test sample mixed with gravel, which overcomes the shortcomings of the traditional consolidation method due to the large size of the sample and the long drainage path, which leads to the slow consolidation of the sample. The time required has changed from several days or even weeks to several hours, which greatly shortens the consolidation time and improves work efficiency.

本发明采用EGK作为电极,解决了传统的采用金属电极产生的电蚀问题,且EGK电极既可作为阴极、也可作为阳极,方便进行电极转换,EGK材料本身还具有排水性能,不需要另设排水体。The present invention uses EGK as the electrode, which solves the problem of electric corrosion caused by the traditional use of metal electrodes, and the EGK electrode can be used as both the cathode and the anode, which is convenient for electrode conversion. The EGK material itself also has drainage performance, and no additional drainage body.

本发明方法可在原有试验仪器上实现,仅在现有三轴仪的基础上增加了电极、导线和电源,应用成本低;本发明操作方便,大三轴试验步骤基本可按照原来的步骤进行,仅在固结时由原来的围压固结变成了电渗固结,没有增加操作难度。The method of the present invention can be realized on the original test instrument, only electrodes, wires and power supply are added on the basis of the existing triaxial instrument, and the application cost is low; the present invention is easy to operate, and the large triaxial test steps can basically be carried out according to the original steps, Only during consolidation, the original confining pressure consolidation is changed to electroosmotic consolidation, without increasing the difficulty of operation.

本发明在大三轴试验中采用电渗法快速固结掺砾料是一种非常有效的方法,技术效果非常好。本发明的其它优点将在下文结合具体实施方式继续描述。The present invention is a very effective method for quickly consolidating gravel-mixed materials by electroosmotic method in a large triaxial test, and the technical effect is very good. Other advantages of the present invention will continue to be described below in conjunction with specific embodiments.

具体实施方式Detailed ways

将本发明的方法用于掺砾心墙料大三轴试验,其仪器装置如图1所示。The method of the present invention is used for the large triaxial test of the gravel-mixed core wall material, and its instrumentation is shown in Figure 1.

一种掺砾心墙料大三轴试验电渗快速固结法,其具体技术步骤为:A large triaxial test electroosmotic rapid consolidation method for gravel-mixed core wall materials, the specific technical steps are:

(1)在大型三轴仪底座3、盖板2上分别预留排水孔9和导线穿越孔道。(1) On the base 3 and the cover plate 2 of the large-scale triaxial instrument, drain holes 9 and passages for wires to pass through are respectively reserved.

(2)在底座3上放置绝缘板7,绝缘板7位于底座3顶面上,直径与试样4相同,为300mm,厚度为1~2mm即可,绝缘板7上预留导线8穿越的小孔,绝缘板7由绝缘硬塑料制作形成,要求变形小,绝缘板7的作用是使下部电极板6与底座3之间绝缘,防止漏电。(2) Place the insulating plate 7 on the base 3. The insulating plate 7 is located on the top surface of the base 3. The diameter is the same as that of the sample 4, which is 300 mm, and the thickness is 1-2 mm. The insulating plate 7 is reserved for the wire 8 to pass through. Aperture, insulating plate 7 is made of insulating hard plastic, requires small deformation, and the effect of insulating plate 7 is to insulate between the lower electrode plate 6 and the base 3 to prevent leakage.

在绝缘板7上放置电极板6,电极板6直径与试样4相同,为300mm,电极板6厚度为1~2cm,电极板6由电动土工合成材料(简称EGK)制成,内部已织入金属丝,可以导电,开有很多上下贯通的针状小孔,方便排水,其作用一方面起到电极通电的作用,另一方面可代替传统三轴试验的透水石,作为排水的通道。Place the electrode plate 6 on the insulating plate 7. The diameter of the electrode plate 6 is the same as that of the sample 4, which is 300mm. The thickness of the electrode plate 6 is 1-2cm. Inserted metal wire, it can conduct electricity, and there are many needle-like holes that penetrate up and down to facilitate drainage. On the one hand, it plays the role of electrifying the electrode, and on the other hand, it can replace the permeable stone in the traditional triaxial test as a drainage channel.

电极板6上放置滤纸5,滤纸5为直径300mm的圆形形状,其作用一方面阻止土颗粒直接进入电极,另一方面使试样4底面排水均匀。The filter paper 5 is placed on the electrode plate 6. The filter paper 5 has a circular shape with a diameter of 300 mm. On the one hand, it prevents soil particles from directly entering the electrode, and on the other hand, it makes the bottom surface of the sample 4 drain evenly.

(3)将下部的导线8穿过底座3和绝缘板7上预留的小孔,与下部电极板6接触连接好,连接时,可直接缠绕在电极板6的金属丝上,能通电即可。导线8要求外表面绝缘。(3) Pass the lower lead wire 8 through the small hole reserved on the base 3 and the insulating plate 7, and contact and connect with the lower electrode plate 6. When connecting, it can be directly wound on the wire of the electrode plate 6, and it can be energized immediately Can. The wire 8 requires insulation on the outer surface.

(4)在底座3上将掺砾心墙料试样4制作好,制作方法同一般的大三轴试验。(4) Fabricate the gravel-mixed core wall material sample 4 on the base 3, and the fabrication method is the same as the general triaxial test.

(5)在试样4顶面上依次放置滤纸5、电极板6和绝缘板7;除放置次序相反外,其他均与步骤(3)相同。(5) Place the filter paper 5, the electrode plate 6 and the insulating plate 7 sequentially on the top surface of the sample 4; except that the placing order is reversed, the others are the same as step (3).

(6)将上部的导线8穿过盖板2和绝缘板7上预留的小孔,导线8与上部电极板6连接好;(6) Pass the upper lead 8 through the small hole reserved on the cover plate 2 and the insulating plate 7, and the lead 8 is connected to the upper electrode plate 6;

(7)将排水管10接好。(7) Connect the drain pipe 10 well.

(8)将两根导线8通过压力室1顶面的小孔穿出,导线8在底座3、盖板2和压力室1的出口处都要设置止水螺栓12,防止水的渗入和渗出。(8) Pass the two wires 8 through the small holes on the top surface of the pressure chamber 1, and the wires 8 must be provided with water-stop bolts 12 at the outlets of the base 3, cover plate 2, and pressure chamber 1 to prevent water from infiltrating and infiltrating out.

将压力室1引出的两根导线8与外部电源11连接,电源11采用直流电源,电压可调节。Connect the two wires 8 leading out of the pressure chamber 1 with an external power supply 11, the power supply 11 adopts a DC power supply, and the voltage can be adjusted.

(9)接通电源11,试样4开始发生电渗固结,根据试样掺砾量的多少和所需的固结时间选择合适的电压。。(9) Turn on the power supply 11, and the sample 4 begins to undergo electroosmotic consolidation, and select an appropriate voltage according to the amount of gravel mixed in the sample and the required consolidation time. .

电渗固结时,孔隙水向上、下电极板6中的阴极运动,通过阴极的排水通道将水排出。本发明中,在试样4两端都设置了排水通道,因此试样4两端的电极板均可作为阳极或阴极。采用EGK材料作为电极板6的另一个好处是既可以作为阳极,也可以作为阴极。在试验的固结过程中,为了使试样4上下固结均匀,可以每隔一定的时间,如15MIN、30MIN、45MIN、60MIN、1.5小时或2小时等,进行一次电极转换,即使两根导线8与电源11正负极的连接相互交换,即完成了电极转换。通过电极转换技术,使试样4分别通过上、下端排水,这样不仅加快了固结速度,还能保证固结均匀。During electroosmotic consolidation, the pore water moves up and down the cathode in the electrode plate 6, and the water is discharged through the drainage channel of the cathode. In the present invention, drainage channels are provided at both ends of the sample 4, so the electrode plates at both ends of the sample 4 can be used as anodes or cathodes. Another benefit of using the EGK material as the electrode plate 6 is that it can be used as both an anode and a cathode. During the consolidation process of the test, in order to make the top and bottom of the sample 4 uniformly consolidated, the electrode switching can be performed every certain time, such as 15MIN, 30MIN, 45MIN, 60MIN, 1.5 hours or 2 hours, even if two wires 8 and the connection of the positive and negative poles of the power supply 11 are interchanged, that is, the electrode conversion is completed. Through the electrode conversion technology, the sample 4 is drained through the upper and lower ends respectively, which not only speeds up the consolidation speed, but also ensures uniform consolidation.

在电渗固结的同时,也可在试样4周围加上围压,使试样4在围压-电渗联合作用下固结,这样能充分发挥两种固结方法的长处,固结速度更快,固结效果更好。At the same time of electroosmotic consolidation, confining pressure can also be added around sample 4, so that sample 4 can be consolidated under the combined action of confining pressure and electroosmosis, which can give full play to the strengths of the two consolidation methods, and consolidate Faster, better consolidation.

本发明的保护范围并不仅仅局限于本实施方式的描述,而是根据权利要求加以限定。The protection scope of the present invention is not limited only to the description of the embodiment, but is defined according to the claims.
