Tunnel defect information is valuable information, however, the existing tunnel defect information is only displayed to the monitoring end in a text form, so that the monitoring end staff cannot intuitively know the real-time state of the current tunnel. Therefore, the application proposes a method for realizing real-time modeling for visualizing and displaying tunnel defect information. According to the technical scheme, the three-dimensional modeling is carried out on the tunnel by utilizing the relevant information of the tunnel obtained in real time, a three-dimensional model of seven diseases such as cracks, base arches, stress conditions, lining deformation, holes, leakage water and falling blocks is created, the corresponding parameter information of various diseases can be displayed in real time according to the position coordinates of the various diseases in the tunnel space, and the function that a monitoring end can check the current three-dimensional display effect of the tunnel according to the real-time tunnel relevant information is realized.
The embodiment of the application describes a real-time three-dimensional modeling method and a real-time three-dimensional modeling system for realizing visualized display of tunnel defects, wherein the technical scheme utilizes the real-time collected related information of a tunnel with defect conditions to construct a three-dimensional visualized tunnel model, and the model can display the actual defect conditions in real time and in an image manner, such as the position of the defect in the tunnel, the defect form scale and other information. The tunnel related information is not limited in how to collect, and the tunnel related information can be acquired manually by a worker or remotely sent by a sensor.
In this example, in order to realize real-time creation of a three-dimensional model showing the state of a tunnel, the data of various sensors in the tunnel acquired by the monitoring platform comprises historical data and real-time monitoring data, the real-time monitoring data is used for analyzing information such as disease type, position, size, property and the like, the three-dimensional model of the disease is created in real time based on the information, the created model and the three-dimensional model of the tunnel are seamlessly fused, and finally the real-time disease state in the tunnel can be intuitively shown. Of course, according to the embodiment of the present application, the historical data may also be displayed, which is not limited herein.
In some embodiments, it is necessary to build a three-dimensional model of the tunnel using tunnel body attribute information (which may be referred to as tunnel attribute information), which provides scene information and model carriers for simulating the tunnel for later image display of tunnel defects, and helps the monitoring end to know the specific form of the tunnel subjected to defect monitoring. The tunnel attribute information can be original tunnel design data, and the establishment of the tunnel three-dimensional model can be realized without any processing.
In some embodiments, if at least one disease condition is found after the tunnel is monitored by the disease, a three-dimensional disease model is built based on the disease detection information collected in real time, and the three-dimensional disease model at this time can be selected from a disease model database created in advance.
In some embodiments, a result guiding model and a disease treatment suggestion method, such as a crack evolution model of how much a crack will expand in the future, a treatment method for the case, an evolution model of stress condition change, a treatment method for the case, and the like, which may be caused later can also be constructed according to disease conditions in combination with empirical data. Therefore, the possible damage results caused by the diseases can be displayed to the monitoring end more intuitively, the monitoring end is helped to take corresponding measures in time, and the disease treatment efficiency is improved.
In the embodiments herein, although the diseases are exemplified by cracks, arching on the substrate, stress conditions, lining deformation, voids, water leakage and chipping, the present application is not limited to the disease conditions, and other possible diseases may be included in addition to the above-mentioned diseases, which are not listed here.
In order to better illustrate embodiments of the present invention, the following description refers to the terms.
Crack and lining deformation: the tunnel lining is an engineering main building which bears stratum pressure and prevents surrounding rocks from deforming and slumping, and the magnitude of the stratum pressure mainly depends on engineering geology, hydrogeology conditions and physical and mechanical properties of the surrounding rocks, and is related to factors such as a construction method, whether supporting lining is timely, the quality of engineering and the like. Due to the action of deformation pressure and loosening pressure, the stratum is longitudinally distributed along the tunnel and the uneven action of mechanical state, the action of temperature and shrinkage stress, the action of surrounding rock expansibility or frost heaving pressure, the action of corrosive medium, the factors considered in construction, the action of cyclic load of an operation vehicle and the like, the tunnel lining structure is cracked and deformed (can be called as lining deformation), and the normal use of the tunnel is affected.
Arching the substrate: the high-speed railways in China are in ballastless track types, when the ballastless tracks are paved in tunnels, the original stress balance state of surrounding rocks at the tunnel bottom is destroyed by the excavation of the tunnels, and the surrounding rocks at the tunnel bottom can enter the stress balance state again after a new stress adjustment period. In the process of adjusting the stress of surrounding rock at the tunnel bottom, the stress adjustment of the surrounding rock can cause the expansion of the expansion rock, so that the volume of the surrounding rock is partially increased, the tunnel bottom of the ballastless track is caused to deform upwards (arch upwards), and the smoothness of the high-speed railway track is seriously influenced.
FIG. 1 illustrates a flow diagram of a real-time three-dimensional modeling method for a tunnel, according to some embodiments.
Before step S110 is performed, the monitoring of the tunnel for the defect is required, and the monitoring may be performed by one or more data acquisition devices, such as a temperature sensor, a laser range finder, a water velocity measuring instrument, a static level, a hydraulic sensor, etc., where the one or more data acquisition devices acquire data of the environmental temperature, the distance, the water velocity, the pressure, etc. in the tunnel, and these data may be transmitted to the monitoring end in real time through a network to directly perform calculation, and the data format stored in the back-end storage system may be a tree structure including basic information of the tunnel and mileage. The corresponding tunnel can store the acquired information and images of the latest date under different installation mileage in the tunnel.
In step S110, relevant information of the tunnel (the relevant information includes tunnel body attribute information and defect monitoring information such as defect type, defect scale, position where defect occurs, and the like) is acquired in real time by, for example, a real-time three-dimensional modeling system for the tunnel. In some embodiments, the defect occurring in the tunnel comprises at least one of: cracks, arching of the substrate, stress conditions, lining deformation, hollows, water leakage and chipping. And the disease scale and the disease occurrence position can be obtained by processing the acquired data.
Specifically, in step S110, the body attribute information of the tunnel acquired in real time preferably includes the belonging route, the tunnel name, the tunnel type, the tunnel length, and the section type. In addition, the tunnel information also comprises monitoring data of all sensors (with numbers as identifiers) under all mileage of each tunnel, and the data are real-time monitored data. The sensor detection data can comprise data such as vertical displacement values of a rail lower structure, deep surrounding rock deformation, surrounding rock contact pressure, steel arch frame stress, steel bar stress, concrete deformation, anchor rod axial force and the like, and data such as strain values of a lining structure, crack widths, steel bar stress, steel arch frame stress, deep surrounding rock deformation and the like. After acquiring the data in real time, the three-dimensional modeling system can perform disease identification, and the identification result can comprise a target type and a disease grade. In some examples, during the identification process, the collected data can be compared with the set early warning values, the early warning values of different grades are different, and the grade of the disease can be determined by the comparison.
Next, in step S120, the real-time three-dimensional modeling system for the tunnel starts creating a three-dimensional model of the tunnel. In the process of creating the tunnel three-dimensional model, it is necessary to create the tunnel three-dimensional model using the tunnel body attribute information in combination with the tunnel attribute information acquired in step S110.
In the application, three-dimensional modeling is to build a three-dimensional model which is the same as an entity in a virtual three-dimensional space according to acquired data by utilizing three-dimensional modeling software. Although 3DMAX modeling software is used in this example, other three-dimensional modeling software is also possible and is not limited herein.
In one example, as shown in fig. 3, the actual length of the tunnel and the tunnel type are first determined by the tunnel attribute information (step S1210), and the tunnel types are divided into single-line single holes and double-line single holes. Then, the tunnel is created in a three-dimensional model library of the tunnel created in advance, and a three-dimensional model of the tunnel per unit length (e.g., 300m or 500 m) is created (S1220), such as a section of the three-dimensional model of the tunnel per unit length shown in fig. 5 (a). Finally, a three-dimensional model of the tunnel matching the actual length of the tunnel is created, that is, a multi-segment tunnel model is loaded according to the actual length of the tunnel, and reference is made to the three-dimensional model of the tunnel shown in fig. 5 (b). It should be noted that the tunnel model library may be created by a three-dimensional technician using a 3DMax tool, including different types of tunnel three-dimensional models per unit length. When an actual tunnel is created, loading a multi-section model according to the input tunnel length to complete the establishment of a three-dimensional model of the tunnel.
Next, in step S130, the real-time three-dimensional modeling system for the tunnel starts creating a three-dimensional model of the lesion. In the process of creating the disease three-dimensional model, it is necessary to create the disease three-dimensional model using the disease detection information in combination with the disease detection information acquired in real time in step S110.
In one example, as shown in fig. 4, a defect condition of the tunnel is first determined (step S1310), the defect condition including information of a defect name, a defect level, a scale, and the like. Then, a three-dimensional model of the corresponding disease is created in a disease three-dimensional model library created in advance (step S1320). It should be noted that the disease three-dimensional model library can also be created by a three-dimensional technician using a 3DMax tool, including three-dimensional models of disease for different disease classes of different disease types. As the three-dimensional models of different diseases of different disease types are created in advance, when the actual disease model is created, only the required three-dimensional model of the disease is required to be called from the model, so that the calculated amount is greatly reduced, and the calculation requirement on a processor is reduced.
Next, in step S140, the position coordinates of each type of defect in the tunnel are determined, and each type of defect three-dimensional model is fused with the tunnel three-dimensional model, so that the fused tunnel three-dimensional model can show the defect situation in space.
The following describes in detail the creation process and model fusion of three-dimensional models of various diseases related to the present application, respectively.
1. Crack modeling and model fusion
When the disease contains a crack, creating a three-dimensional model of the crack in a disease three-dimensional model library. Specifically, different three-dimensional models of the cracks are created according to the size of the cracks, the position coordinates of the crack three-dimensional models in the tunnel are determined according to the mileage of the crack defects, the crack three-dimensional models are fused with the tunnel three-dimensional models, and the actual positions and the size of the crack defects in the tunnel are displayed on the fused tunnel three-dimensional models. The fusion of the two models can be realized by loading the disease three-dimensional model and corresponding information thereof on the tunnel three-dimensional model. It should be noted that, the expression "mileage" is: mileage plus + -location, indicating left or right hole, location indicating distance from top of hole. If the crack is acquired by a sensor, the mileage can be obtained according to the mileage of the sensor installed in the tunnel and the distance between the sensor and the crack.
In the disease three-dimensional model library, different fracture models have been created in advance according to the lengths of the fractures. In the crack three-dimensional model library, models of different levels are displayed from small to large in display length, for example, the display length is expressed as follows: 0m to 1 m, level 1 model; 1 meter to 2 meters, level 2 model; 2m to 3 m, 3-stage model; 3 meters to 4 meters, level 4 model; 4 m to 5m, 5-stage model; greater than 5 meters, model 6. In creating the actual fracture model, a matching three-dimensional model of the fracture is selected from among the three-dimensional models of the fracture according to the actual lengths of the fracture, for example, a three-dimensional model of a fracture of a level selected from a library of three-dimensional models of the fracture according to the disease monitoring information is shown in fig. 6 (a). And the fusion model shown in fig. 6 (b) can be obtained after the model is fused with the tunnel three-dimensional model, and the position, the distribution condition and the size of the crack can be intuitively seen in the model.
In addition, besides the fact that different crack models can be created according to the lengths of the cracks, crack width factors can be added, and the fact that the crack models are created through the two factors is more accurate in performance.
2. Substrate arch modeling and model fusion
When the disease comprises a substrate arching situation, creating a substrate arching three-dimensional model in a disease three-dimensional model library. Specifically, different substrate arch three-dimensional models are created according to the size of the arch width, the position coordinates of the substrate arch three-dimensional models in the tunnel are determined according to the mileage of the substrate arch damage, the substrate arch three-dimensional models are fused with the tunnel three-dimensional models, and the actual position and the size of the substrate arch damage in the tunnel are displayed on the fused tunnel three-dimensional models. The fusion of the two models can be realized by an information loading mode, for example, a mode of loading the disease three-dimensional model and corresponding information thereof on the tunnel three-dimensional model. The expression "mileage" here is mileage number plus ±, ±indicates whether to the left or right of the hole.
In the disease three-dimensional model library, different arch-on-substrate models are created in advance according to the arch-on amplitude. In a base arch three-dimensional model library, models with different levels show different arch magnitudes from small to large, for example: 0cm to 5cm, stage 1 model; 5cm to 10cm, stage 2 model; 10cm to 15cm,3 stage model; 15cm to 20cm, stage 4 model; 20cm to 30cm, 5-stage model; 30cm or more, 6-stage model. In creating the actual arch-on-substrate model, a matching arch-on-substrate three-dimensional model is selected from the database according to the height of the arch-on-amplitude, for example, a tunnel three-dimensional model incorporating the arch-on-substrate three-dimensional model may be shown as shown in fig. 7. The position, distribution and specific camber of the substrate can be visually seen in the model.
3. Stress condition modeling and model fusion
