[0025] The embodiments of the application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the application, and cannot be understood as a limitation of the application.

[0026] In order to facilitate understanding, first introduce the terms related to the application.

[0027] 1. Underground passage

[0028] The underground passage referred to in the present application refers to various underground passages and tunnels and the like structures widely used in the mining and transportation industries. Due to their location underground, these structures generally have poor lighting conditions, humidity and complex environments, which pose challenges to computer vision-based monitoring techniques. Common underground passage structures include mine tunnels, subway tunnels, highway tunnels and other underground works, which need to maintain structural stability for a long time to cope with geological changes, construction disturbances and other external influences.

[0029] 2. Passage deformation

[0030] Passage deformation refers to the inward displacement of the inner wall of the underground passage structure under stress or external environmental changes. It is manifested as displacement of different parts, such as roof subsidence, floor heave (upward bulging of the bottom) and rib heave (inward bulging of the sidewall). The scale and location of these deformations vary, and they can cause small displacements in a small area or significant deformations in a large area, seriously affecting structural safety. Therefore, effective monitoring and early warning of these deformations are of great significance to structural maintenance and disaster prevention.

[0031] In recent years, with the rise of advanced technologies such as computer vision, laser scanning and multi-modal fusion computing, the monitoring methods for underground passage structures have become more efficient and accurate. These technologies can capture subtle deformations of the inner wall of the passage in real time, providing accurate data and visual analysis, greatly improving the efficiency and effectiveness of monitoring. However, such methods usually rely on a large amount of high-quality training data, especially in practical applications that require analysis through machine learning or deep learning models. However, in reality, the deformation phenomena of underground passages are rare and difficult to reproduce in large quantities, making data acquisition challenging. Existing three-dimensional model test systems for tunnels and underground structures are usually equipped with three-dimensional pressure systems that can load the underground structure in all directions, simulating stress distribution and structural response under real working conditions. Such systems are mainly used to study the mechanical properties, load-bearing capacity and optimization design of underground structures. However, their functions are limited to mechanical experiments and cannot be used to simulate and study the subtle deformations of underground structures, especially in combination with advanced deformation monitoring methods such as computer vision and laser scanning. Therefore, the construction of experimental devices and methods to simulate the deformation of the inner wall of underground passages has become an important research direction, helping to fill this data gap and promote the development of monitoring technology.

[0032] In summary, the existing experimental devices for studying underground passage structures generally have the following problems:

[0033] 1. Static simulation is the main problem, and dynamic deformation is lacking. Most experimental devices can only simulate static structures and cannot reflect the dynamic deformation process of the structure under external force, limiting in-depth study of the deformation process.

[0034] 2. Lack of active deformation device: Existing equipment usually cannot actively initiate and control deformation, making it difficult to simulate deformation characteristics under various complex working conditions, affecting the development and verification of deformation monitoring technology.

[0035] 3. Difficulty in data acquisition: There are limited experimental equipment for underground tunnel deformation, especially for actual deformation experimental data that is difficult to reproduce in large quantities, which limits the application of data-driven technologies such as machine learning.

[0036] 4. Cannot effectively combine advanced monitoring technology: Existing three-dimensional pressure system experimental methods cannot be combined with computer vision, laser scanning, and other precision monitoring technologies, making it difficult to conduct comprehensive deformation monitoring experiments.

[0037] 5. High experimental cost: Some equipment is complex and expensive, with high usage costs and long experimental periods, making it unsuitable for large-scale deformation monitoring research and equipment optimization.

[0038] To solve the above problems, the embodiments of the present application provide an experimental system for an underground tunnel, which includes a shell model of the underground tunnel, a first air bag, a second air bag, a first inflation device, and a first monitoring module. By inflating the second air bag, the first air bag is deformed to simulate the deformation of the underground tunnel. The deformation can be actively initiated, and the dynamic and real deformation information of the first air bag over a period of time can be monitored to simulate the dynamic deformation of the underground tunnel. Compared with related art, which can only simulate the static deformation of the underground tunnel, the richness of the simulated deformation information of the underground tunnel is improved.

[0039] Further, the embodiments of the present application also provide an experimental method for an underground tunnel. The second air bag is inflated to squeeze the first air bag. During the inflation of the second air bag, the real deformation information of the first air bag at N time points is monitored, and based on the real deformation information of the first air bag at the i-th time point, the simulation deformation information of the underground tunnel at the i-th time point is obtained. In this way, by inflating the second air bag, the first air bag is deformed to simulate the deformation of the underground tunnel. The deformation can be actively initiated, and the dynamic and real deformation information of the first air bag over a period of time can be monitored to simulate the dynamic deformation of the underground tunnel. Compared with related art, which can only simulate the static deformation of the underground tunnel, the richness of the simulated deformation information of the underground tunnel is improved.

[0040] The experimental system, method, device, electronic device, and storage medium for an underground tunnel of the embodiments of the present application are described below with reference to the accompanying drawings.

[0041] Figure 1 FIG. 1 is a schematic diagram of an experimental system of an underground passage according to an embodiment of the present application.

[0042] As shown in FIG. 1, the experimental system of the underground passage 100 includes a shell model of an underground passage 1, a first air bag 2, a second air bag 3, a first air filling device 4, and a first monitoring module 5. Figure 1 The first air bag 2 is tightly attached to the inner wall of the shell model 1, and the second air bag 3 is located between the first air bag 1 and the inner wall of the shell model 1. It can be understood that a part of the outer surface of the first air bag 2 is tightly attached to the inner wall of the shell model 1, and the second air bag 3 is located between another part of the outer surface of the first air bag 1 and the inner wall of the shell model 1.

[0043] The first air filling device 4 is used to inflate the second air bag 3 so that the second air bag 3 extrudes the first air bag 2. The first monitoring module 5 is used to monitor the real deformation information of the first air bag 2 at N time points, wherein N is an integer greater than 1.

[0044] It should be noted that the shell model 1 is used to simulate the external structure (also called the outer wall) of the underground passage, the first air bag 2 is used to simulate the internal structure (including the inner wall and air of the underground passage) of the underground passage, the first air bag 2 is also called an inner bag, and the real deformation information of the first air bag 2 is used to obtain the simulation deformation information of the underground passage. For related content, please refer to the following embodiments, which will not be described here.

[0045] During the inflation of the second air bag 3, the second air bag 3 can extrude the first air bag 2, so that the first air bag 2 deforms. With the passage of time, the degree of extrusion of the second air bag 3 on the first air bag 2 is greater, and thus the degree of deformation of the first air bag 2 is also greater. The real deformation information of the first air bag 2 at different time points can be different, that is, the real deformation information of the first air bag 2 at N time points is the dynamic and real deformation information of the first air bag 2 within a period of time.

[0046] The deformation information is not limited too much, such as including deformation type, deformation amount (such as displacement, strain, inclination angle), shape before deformation, shape after deformation, deformation position, etc. The deformation type includes bias deformation, roof subsidence, roof cracking, floor heave, sidewall cracking, and rib spalling.

[0047] The deformation information is not limited too much, such as including deformation type, deformation amount (such as displacement, strain, inclination angle), shape before deformation, shape after deformation, deformation position, etc. The deformation type includes bias deformation, roof subsidence, roof cracking, floor heave, sidewall cracking, and rib spalling.

[0048] In the present application, the second air bag is inflated to deform the first air bag to simulate the deformation of the underground tunnel, which can actively induce deformation and monitor the dynamic and real deformation information of the first air bag within a period of time, and further obtain the dynamic and simulated deformation information of the underground tunnel within a period of time, which can reflect the dynamic deformation process of the underground tunnel under external force, that is, the dynamic deformation of the underground tunnel can be simulated. Compared with the related art which can only simulate the static deformation of the underground tunnel, the richness of the simulated deformation information of the underground tunnel is improved, which helps to realize in-depth research on the deformation process of the underground tunnel. In addition, batch and large-scale collection of real deformation information can also be realized.

[0049] The simulated deformation information of the underground tunnel refers to the deformation information of the underground tunnel obtained according to the real deformation information of the first air bag in an experimental environment.

[0050] When at least one information in the shape of the first air bag before and after deformation, the arrangement position of the second air bag and the shape after inflation changes, the deformation type, deformation scale and deformation position of the simulated underground tunnel may all change. For example, Figure 2 Four underground tunnel experimental systems are shown, and at least one information in the arrangement position of the second air bag 3 and the shape after inflation is different in the four underground tunnel experimental systems. It should be noted that the first inflation device 4 and the first monitoring module 5 are not shown in Figure 2 .

[0051] In the present application, the first air bag with adjustable shape and the second air bag with adjustable shape and arrangement position are used to realize precise control of the deformation type, deformation scale and deformation position of the simulated underground tunnel, that is, the deformation is controllable. Unlike the three-dimensional pressure system in the prior art which can only study mechanical properties, the experimental system of the present application can actively induce and control deformation, such as simulating deformation of different types, different scales and different positions (such as roof, bottom and side) of the underground tunnel, which can more flexibly simulate various complex deformation scenarios under actual working conditions.

[0052] Optionally, as Figure 1 shown, the underground tunnel experimental system 100 further comprises a second monitoring module 6, and the second monitoring module 6 is used to monitor the original deformation information of the first air bag 2 at N time points. The second monitoring module 6 is a deformation monitoring module of the underground tunnel.

[0053] It should be noted that the first monitoring module 5 and the second monitoring module 6 are different monitoring modules, and the monitoring accuracy of the first monitoring module 5 is higher than that of the second monitoring module 6. The second monitoring module 6 refers to a deformation monitoring module of the underground passage in the real environment, which is used to monitor the real deformation information of the underground passage, that is, the real deformation information of the underground passage refers to the deformation information of the underground passage monitored by the second monitoring module 6 in the real environment. The real deformation information of the first air bag 2 at the same time may be the same as the original deformation information, or may be different.

[0054] The real deformation information of the first air bag 2 at N time points and the original deformation information of the first air bag 2 at N time points are used to optimize the second monitoring module 6, and the related content can be referred to in the following embodiments, which will not be repeated here.

[0055] The first monitoring module 5 and the second monitoring module 6 are not limited. For example, the first monitoring module 5 includes a convergence meter, a total station, a strain gauge, an inclinometer, etc. The second monitoring module 6 includes a camera, a laser scanner, a radar, a deformation monitoring model, etc. The deformation monitoring model includes a mechanism model, a data-driven model, etc. The data-driven model includes a time series model, a machine learning model (such as a deep learning model, a reinforcement learning model), a statistical regression model, etc.

[0056] Optionally, the second monitoring module 6 includes at least one deformation monitoring model in a computer vision model, a laser scanning model, and a multi-modal fusion model. Thus, in addition to monitoring the real deformation information of the first air bag, precise monitoring technologies such as computer vision, laser scanning, and multi-modal fusion can also be used to monitor the original deformation information of the first air bag, and comprehensive deformation monitoring experiments can be performed.

[0057] In this embodiment, the dynamic and original deformation information of the first air bag over a period of time can be monitored, which improves the richness of the obtained deformation information. In addition, batch and large-scale collection of original deformation information can also be realized. For example, the real deformation information, the original deformation information, and the experimental environment information (such as loading conditions and environmental change information) can be combined to generate a deformation data set, which fills the gap of insufficient data in actual engineering due to rare deformation and difficulty in reproduction, and provides a solid foundation for future algorithm development and verification. For example, the data set plays an important role in the algorithm research and software and hardware optimization of computer vision, laser scanning, and multi-modal fusion. By providing accurate training data, the performance of the algorithm in underground passage deformation monitoring can be significantly improved, the research and development of the monitoring system can be accelerated, and the progress of intelligent deformation monitoring technology can be promoted.

[0058] Optionally, as Figure 1As shown, the experimental system 100 of the underground passage further comprises a second inflating device 7 for inflating the first air bag 2 to adjust the shape of the first air bag 2 to the shape before the first air bag 2 is deformed, and to make the first air bag 2 tightly fit the inner wall of the shell model 1.

[0059] It should be noted that the shape before the first air bag 2 is deformed is also the shape after the first air bag 2 is inflated. The first inflating device 6 and the second inflating device 7 can be the same or different, which is not limited here. For example, the inflating accuracy of the first inflating device 6 is higher than that of the second inflating device 7. The first inflating device 6 and the second inflating device 7 are not limited here.

[0060] Optionally, the first inflating device 6 comprises a mass flow meter, a volume flow meter (such as a vortex flow meter), an air pressure sensor, a controller, an air pump, a compressor, etc. The mass flow meter is used to monitor the mass of air entering the second air bag 3, the volume flow meter is used to monitor the volume of air entering the second air bag 3, the air pressure sensor is used to monitor the air pressure of the second air bag 3, and the controller is used to adjust the operating parameters of at least one of the air pump and the compressor based on the target inflation information of the second air bag 3 and the monitoring results of at least one of the mass flow meter, the volume flow meter and the air pressure sensor, to realize accurate control of the inflation process of the second air bag 3 and ensure that the inflation accuracy reaches the milliliter level.

[0061] Optionally, the second inflating device 7 comprises an air pressure sensor, a controller, an air pump, etc. The air pressure sensor is used to monitor the air pressure of the first air bag 2, and the controller is used to adjust the operating parameters of the air pump based on the air pressure of the first air bag 2, to realize accurate control of the inflation process of the first air bag 2 and to automatically supplement air to the first air bag 2.

[0062] Optionally, at least one of the first air bag 2 and the second air bag 3 is made of a flexible material. It should be noted that the flexible material is not limited here, for example, at least one of the first air bag 2 and the second air bag 3 is made of a flexible material with good air tightness and certain ductility, such as ETFE film (ethylene-tetrafluoroethylene copolymer film), PTFE film (polytetrafluoroethylene film), PVC film (polyvinyl chloride film), TPU (thermoplastic polyurethane), etc.

[0063] Optionally, the first air bag 2 and the second air bag 3 are made of the same material.

[0064] Optionally, the shell model 1 is detachable, so as to flexibly arrange the second air bag 3. For example, a partial shell of the shell model 1 can be detached from the outside of the shell model 1, and the second air bag 3 can be placed between the first air bag 2 and the inner wall of the shell model 1 at the detached position, and then the detached partial shell can be mounted on the shell model 1. It can be understood that if the arrangement position of the second air bag 3 changes, the detachment position of the shell model 1 needs to be changed.

[0065] Optionally, the experimental system 100 of the underground passage further includes a skeleton (also called a keel) model of the underground passage, and the shell model is arranged on the inside of the skeleton model.

[0066] For example, a skeleton model of the underground passage is built by using materials such as U-shaped steel, channel steel or steel pipes at certain intervals, so as to ensure that the skeleton model is firm and has good deformation resistance. The U-shaped steel is a kind of steel with a cross section like the English letter "U". The shell model is fixed on the inside of the skeleton model, and the material of the shell model is required to be firm and not easy to deform. In order to facilitate subsequent experiments, the shell model is preferably fixed by using bolts, and relatively light plates are used.

[0067] In summary, the experimental system of the underground passage provided in the embodiments of the present application includes a shell model of the underground passage, a first air bag, a second air bag, a first inflation device and a first monitoring module. The second air bag is inflated to make the first air bag deform to simulate the deformation of the underground passage. The deformation can be actively induced, and the dynamic and real deformation information of the first air bag within a period of time can be monitored to simulate the dynamic deformation of the underground passage. Compared with the related art which can only simulate the static deformation of the underground passage, the richness of the simulated deformation information of the underground passage is improved.

[0068] The embodiments of the present application provide an experimental method of an underground passage. The experimental method is applicable to the experimental system of the underground passage provided in the foregoing embodiments.

[0069] As shown in Figure 3 the method can include the following steps:

[0070] S301, the second air bag is inflated to press the first air bag.

[0071] S302, during the inflation of the second air bag, the real deformation information of the first air bag at N time points is monitored, and N is an integer greater than 1.

[0072] The related content of steps S301-S303 can be referred to the foregoing embodiments, which will not be described here.

[0073] S303, based on the real deformation information of the first air bag at the i th time point, the simulation deformation information of the underground passage at the i th time point is obtained, and i is a positive integer not greater than N.

[0074] For example, taking N=5 as an example, during the process of inflating the second air bag, the real deformation information of the first air bag at 10 time points is monitored, based on the real deformation information of the first air bag at the first time point, the simulation deformation information of the underground tunnel at the first time point is obtained, based on the real deformation information of the first air bag at the second time point, the simulation deformation information of the underground tunnel at the second time point is obtained, based on the real deformation information of the first air bag at the third time point, the simulation deformation information of the underground tunnel at the third time point is obtained, based on the real deformation information of the first air bag at the fourth time point, the simulation deformation information of the underground tunnel at the fourth time point is obtained, based on the real deformation information of the first air bag at the fifth time point, the simulation deformation information of the underground tunnel at the fifth time point is obtained.

[0075] Optionally, based on the real deformation information of the first air bag at the i-th time point, the simulation deformation information of the underground tunnel at the i-th time point is obtained, including taking the real deformation information of the first air bag at the i-th time point as the simulation deformation information of the underground tunnel at the i-th time point.

[0076] It can be understood that the shell model of the underground tunnel and the first air bag are respectively used to simulate the external structure and the internal structure of the underground tunnel, if the shell model, the first air bag and the underground tunnel have high similarity in material, geometric shape (including size) and stress condition, at this time the real deformation information of the first air bag can be regarded as the simulation deformation information of the underground tunnel, then the real deformation information of the first air bag is directly taken as the simulation deformation information of the underground tunnel.

[0077] On the contrary, if at least one of the material, geometric shape and stress condition of the shell model, the first air bag and the underground tunnel has a large difference, at this time the real deformation information of the first air bag cannot be regarded as the simulation deformation information of the underground tunnel, then the real deformation information of the first air bag needs to be converted to obtain the simulation deformation information of the underground tunnel.

[0078] Optionally, based on the real deformation information of the first air bag at the i-th time point, the simulation deformation information of the underground tunnel at the i-th time point is obtained, including based on the correlation between the real deformation information and the simulation deformation information, and the real deformation information of the first air bag at the i-th time point, the simulation deformation information of the underground tunnel at the i-th time point is obtained. Thus, the correlation between the real deformation information and the simulation deformation information can be considered, and the real deformation information of the first air bag at a certain time is considered to obtain the simulation deformation information of the underground tunnel at the time.

[0079] It should be noted that the correlation relationship is not limited too much, such as including a linear relationship, a nonlinear relationship, a polynomial curve, a function relationship expressed by a function expression, a corresponding relationship between a value range, etc.

[0080] In summary, according to the experimental method of the underground passage provided in the embodiments of the present application, the second air bag is inflated to extrude the first air bag, the real deformation information of the first air bag at N time points is monitored during the inflation of the second air bag, and the simulation deformation information of the underground passage at the i th time point is obtained based on the real deformation information of the first air bag at the i th time point. Thus, by inflating the second air bag to make the first air bag deform to simulate the deformation of the underground passage, the deformation can be actively induced, and the dynamic and real deformation information of the first air bag within a period of time can be monitored to simulate the dynamic deformation of the underground passage. Compared with the related art which can only simulate the static deformation of the underground passage, the richness of the simulated deformation information of the underground passage is improved.

[0081] In addition, batch and large-scale collection of real deformation information can also be realized.

[0082] In the above embodiments, regarding the steps before the inflation of the second air bag in step S301, the steps can be combined with Figure 4 Further understanding. Figure 4 Another flowchart of an experimental method of an underground passage provided by the embodiments of the present application is shown. As shown in the figure, the method can include the following steps: Figure 4

[0083] S401, the second air bag is arranged between the first air bag and the inner wall of the shell model of the underground passage.

[0084] For example, if the arrangement position of the second air bag is between the first air bag and the left inner wall of the shell model, the left shell of the shell model 1 can be disassembled from the outside of the shell model 1, and the second air bag can be placed between the first air bag and the left inner wall of the shell model from the local disassembly position. Then, the disassembled left shell is installed on the shell model.

[0085] For example, if the arrangement position of the second air bag is between the first air bag and the lower inner wall of the shell model, the lower shell of the shell model 1 can be disassembled from the outside of the shell model 1, and the second air bag can be placed between the first air bag and the lower inner wall of the shell model from the local disassembly position. Then, the disassembled lower shell is installed on the shell model.

[0086] S402, the first air bag is inflated to tightly adhere to the inner wall of the shell model.

[0087] S403, the second air bag is inflated to extrude the first air bag.​

[0088] S404, monitoring real deformation information of the first air bag at N time points during the process of inflating the second air bag, N being an integer greater than 1.

[0089] S405, obtaining simulated deformation information of the underground tunnel at the i-th time point based on the real deformation information of the first air bag at the i-th time point, i being a positive integer not greater than N.

[0090] The related content of steps S402-S405 can be referred to the above embodiments, which will not be repeated here.

[0091] In summary, according to the experimental method of the underground tunnel in the embodiments of the present application, before inflating the second air bag, the second air bag is arranged between the first air bag and the inner wall of the shell model, and the first air bag is inflated to tightly fit the inner wall of the shell model.

[0092] On the basis of any of the above embodiments, the method further comprises determining experimental information based on the set deformation information of the underground tunnel, wherein the experimental information comprises at least one of the shape of the first air bag before deformation, the shape of the first air bag after deformation, the shape of the second air bag after inflation, and the arrangement position of the second air bag. Thus, at least one of the shape of the first air bag before deformation, the shape of the first air bag after deformation, the shape of the second air bag after inflation, and the arrangement position of the second air bag can be determined considering the set deformation information of the underground tunnel, so as to realize the simulation of the set deformation information of the underground tunnel.

[0093] It should be noted that the set deformation information is not limited too much, such as deformation type, deformation scale, deformation position, etc. In the present application, at least one of the shape of the first air bag before and after deformation, the arrangement position of the second air bag and the shape of the second air bag after inflation can be adjusted to accurately control the deformation type, deformation scale and deformation position of the simulated underground tunnel, i.e. the deformation is controllable. For example, the deformation of different types, different scales and different positions (such as the roof, the bottom and the side) of the underground tunnel can more flexibly simulate various complex deformation scenarios under actual working conditions.

[0094] In the present embodiment, the experimental information is determined based on the set deformation information of the underground tunnel, including the following possible implementation manners:

[0095] Manner 1, determining the shape of the first air bag before deformation and the shape of the first air bag after deformation based on the set deformation information, and determining the shape of the second air bag after inflation and the arrangement position based on the shape of the first air bag before deformation and the shape of the first air bag after deformation.

[0096] Optionally, determining the shape of the first air bag before deformation and the shape of the first air bag after deformation based on the set deformation information comprises determining the shape of the underground passage before deformation and the shape of the underground passage after deformation based on the set deformation information, obtaining the shape of the first air bag before deformation based on the shape of the underground passage before deformation, and obtaining the shape of the first air bag after deformation based on the shape of the underground passage after deformation.

[0097] In some examples, obtaining the shape of the first air bag before deformation based on the shape of the underground passage before deformation comprises taking the shape of the underground passage before deformation as the shape of the first air bag before deformation.

[0098] It can be understood that if the first air bag and the internal structure of the underground passage have high similarity in geometry, the shape of the underground passage before deformation can be directly taken as the shape of the first air bag before deformation.

[0099] On the contrary, if the first air bag and the internal structure of the underground passage have great difference in geometry, for example, the first air bag is a scaled model of the internal structure of the underground passage, the shape of the first air bag before deformation needs to be obtained by converting the shape of the underground passage before deformation.

[0100] In some examples, obtaining the shape of the first air bag before deformation based on the shape of the underground passage before deformation comprises obtaining the shape of the first air bag before deformation based on the correlation between the shape of the underground passage and the shape of the first air bag and the shape of the underground passage before deformation. For example, if there is a scaling relationship between the shape of the underground passage and the shape of the first air bag, the shape of the first air bag before deformation can be obtained by scaling the shape of the underground passage before deformation.

[0101] It should be noted that the related content of obtaining the shape of the first air bag after deformation based on the shape of the underground passage after deformation can refer to the related content of obtaining the shape of the first air bag before deformation based on the shape of the underground passage before deformation in the above embodiments, which will not be described here.

[0102] Optionally, determining the shape of the second air bag after inflation based on the shape of the first air bag before deformation and the shape of the first air bag after deformation comprises splitting the shape of the first air bag before deformation into the shape of the first air bag after deformation and a target shape, and taking the target shape as the shape of the second air bag after inflation. It can be understood that the shape of the first air bag before deformation in this embodiment can be regarded as being composed of the shape of the first air bag after deformation and the shape of the second air bag after inflation.

[0103] Optionally, determining the shape of the second air bag after inflation based on the shape of the first air bag before deformation and the shape of the first air bag after deformation comprises obtaining a deformation amount of the first air bag based on the shape of the first air bag before deformation and the shape of the first air bag after deformation, and determining the shape of the second air bag after inflation based on the deformation amount of the first air bag.

[0104] In some examples, determining the shape of the second air bag after being inflated based on the deformation amount of the first air bag includes obtaining the shape of the second air bag after being inflated based on a correlation between the deformation amount of the first air bag and the shape of the second air bag after being inflated and the deformation amount of the first air bag.

[0105] Optionally, determining the arrangement position based on the shape of the first air bag before deformation and the shape of the first air bag after deformation includes obtaining a deformation position of the first air bag based on the shape of the first air bag before deformation and the shape of the first air bag after deformation, and taking a position between the deformation position of the first air bag and the inner wall of the shell model as the arrangement position.

[0106] Optionally, the method further includes obtaining the experimental information based on a correlation between the set deformation information and the experimental information and the set deformation information.

[0111] The related content of steps S501-S503 can be referred to the above embodiments, which will not be repeated here.

[0112] In the embodiments, the dynamic and original deformation information of the first air bag in a period of time can be monitored, which improves the richness of the obtained deformation information, and in addition, batch and large-scale collection of the original deformation information can be realized.

[0113] S504, optimizing the second monitoring module based on the real deformation information of the first air bag at the N time points and the original deformation information of the first air bag at the N time points.

[0114] Optionally, the second monitoring module includes at least one deformation monitoring model in a computer vision model, a laser scanning model and a multi-modal fusion model.

[0115] ​The second monitoring module is optimized based on the real deformation information of the first air bag at the N time points and the original deformation information of the first air bag at the N time points, including associating the real deformation information of the first air bag at the i-th time point with the original deformation information of the first air bag at the i-th time point to obtain a training sample, and training the deformation monitoring model based on the training sample. In this way, the real deformation information and the original deformation information of the first air bag at the same time point can be associated to obtain a training sample to train the deformation monitoring model, thereby improving the monitoring accuracy of the deformation monitoring model.

[0116] It should be noted that the deformation monitoring model is trained based on the training sample, and any model training method in the related art can be used to implement this, which is not limited here. For example, a loss function of the deformation monitoring model can be obtained based on multiple training samples, and the deformation monitoring model is trained based on the loss function. It should be noted that the loss function is not limited, for example, it can include CE (Cross Entropy, Cross Entropy), MSE (Mean-Square Error, Mean-Square Error), KL (Kullback-Leibler) divergence, contrast loss function, etc.

[0117] Optionally, the second monitoring module includes at least one deformation monitoring device of a camera, a laser scanner, and a radar, and the second monitoring module is optimized based on the real deformation information of the first air bag at the N time points and the original deformation information of the first air bag at the N time points, including constructing a calibration model of the deformation monitoring device based on the real deformation information of the first air bag at the N time points and the original deformation information of the first air bag at the N time points, and adjusting the parameters of the deformation monitoring device based on the calibration model.

[0118] Optionally, the second monitoring module is optimized based on the real deformation information of the first air bag at the N time points and the original deformation information of the first air bag at the N time points, including optimizing the second monitoring module based on the real deformation information of the first air bag at the N time points, the original deformation information of the first air bag at the N time points, and experimental environment information. In this way, the dynamic and real deformation information of the first air bag over a period of time, the dynamic and original deformation information, and the experimental environment information can be considered to optimize the second monitoring module, the influence of the experimental environment information on the monitoring result of the second monitoring module can be considered, and the monitoring accuracy of the second monitoring module is further improved.

[0119] In summary, according to the experimental method of the underground passage provided in the embodiment of the present application, in the process of inflating the second air bag, the original deformation information of the first air bag at N time points is monitored by the second monitoring module, and the second monitoring module is optimized based on the real deformation information of the first air bag at N time points and the original deformation information of the first air bag at N time points. Therefore, the dynamic and real deformation information of the first air bag within a period of time and the dynamic and original deformation information can be comprehensively considered to optimize the second monitoring module, which helps to improve the monitoring accuracy of the second monitoring module and is suitable for optimization scenarios of computer vision, laser scanning and multi-modal fusion technology.

[0121] Firstly, the type and scale of the tunnel deformation to be simulated are analyzed, the shape of the first air bag before deformation and the required deformation amount are determined, and then the shape and layout position of the second air bag are designed according to the shape of the first air bag before and after deformation.

[0122] Secondly, the hard shell of the tunnel at the corresponding position is removed from the outside of the simulated tunnel, the designed second air bag is placed in the designed layout direction, and then the hard shell is reinstalled.

[0123] Thirdly, the first air bag is inflated to reach the required pre-deformation shape, and then the second air bag is quantitatively inflated by the precise inflation system to make the first air bag have the required deformation amount. Before and after the second inflation, the change amount is measured as the true value of deformation by the precise measurement equipment, and the original data is obtained by using advanced technologies such as computer vision, laser scanning and multi-modal fusion calculation for underground dense measurement, which is used for algorithm optimization calculation.
