Technical Field

[0001] The present invention relates to the technical field of tunnel engineering, and in particular to an analysis method, device, equipment, medium and product for the risk of water abundance of surrounding rocks. Background Art

[0002] During the construction of tunnel projects, the water-richness of the surrounding rock (surrounding rock) at the construction site is one of the key factors affecting project safety and construction efficiency. The water-richness of the surrounding rock at the construction site refers to the richness of water in the surrounding rocks at the construction site of the tunnel project, and is mainly used to describe the occurrence of groundwater in the surrounding rocks. Especially under karst geological conditions, sudden water and mud gushing disasters have become one of the most serious disasters in tunnel construction, which not only causes huge economic losses, but may also cause serious casualties.

[0003] In order to prevent disasters caused by the high water content of the surrounding rock, it is necessary to predict the water content of the surrounding rock. The advanced geological prediction methods in related technologies include drilling, geological radar and transient electromagnetic method. Although these prediction methods can obtain water content information to a certain extent, their accuracy is low and it is difficult to meet the construction requirements under complex geological conditions. Summary of the invention

[0004] In view of this, the present invention provides a method, device, equipment, medium and product for analyzing the water-richness risk of surrounding rocks, so as to solve the problem of low accuracy of water-richness information obtained by traditional forecasting means.

[0006] The present invention uses a water-richness index adaptation table to query the first water-richness index corresponding to multiple surrounding rock samples, and constructs a water-richness database of multiple surrounding rock samples according to the first water-richness index corresponding to multiple surrounding rock samples. The present invention stores the first water-richness index corresponding to multiple surrounding rock samples and their three-dimensional spatial coordinates in the water-richness database, providing a comprehensive and orderly data basis for subsequent prediction and analysis. The present invention uses the constructed water-richness database to predict the second water-richness index of multiple target surrounding rocks to be predicted for water-richness other than the surrounding rock samples, which can more accurately reflect the water-richness of the target surrounding rocks and provide a more reliable basis for engineering decision-making. The present invention performs risk analysis on the target point cloud data in the target point cloud model according to the second water-richness index of multiple target surrounding rocks, obtains the risk level corresponding to the target point cloud data, and converts complex geological information into intuitive risk levels, so that engineering personnel can clearly understand the degree of water-richness risk in different parts of the tunnel, so as to take corresponding prevention and response measures in a targeted manner to reduce engineering risks and costs. Compared with the related art, the present invention predicts the water-richness index of multiple target surrounding rocks to determine the water-richness risks of multiple target surrounding rocks, thereby improving the accuracy of water-richness risk analysis, being more suitable for construction requirements under complex geological conditions, and improving the safety of tunnel engineering construction.

[0008] In an optional embodiment, a water-richness database of multiple surrounding rock samples is constructed based on the first water-richness indexes corresponding to the multiple surrounding rock samples, including: obtaining the three-dimensional spatial coordinates of the multiple surrounding rock samples, associating the first water-richness index of each surrounding rock sample with the three-dimensional spatial coordinates to obtain an association result; and storing the association result to obtain a water-richness database.

[0009] The present invention achieves the organic integration of the water-richness index and the spatial position information by acquiring the three-dimensional spatial coordinates of multiple surrounding rock samples and associating them with the first water-richness index.

[0012] The present invention determines the characteristic parameters of the fuzzy cloud model according to the second water-richness index of multiple target surrounding rocks, uses the fuzzy cloud model to perform uncertainty analysis, fully considers the complexity and uncertainty factors of the geological environment, and can more truly reflect the actual situation of the water-richness risk of the surrounding rocks, thereby improving the accuracy of subsequent water-richness risk analysis. The present invention simulates the cloud droplet generation process and counts the number according to the characteristic parameters, and then determines the risk probability corresponding to each preset risk level, avoiding the arbitrariness of subjective judgment, making the determination of the risk level more accurate and reliable.

[0013] In an optional embodiment, based on the number of cloud droplets corresponding to multiple preset risk levels, a risk probability corresponding to each preset risk level is generated, including: taking the quotient of the number of cloud droplets corresponding to each preset risk level and the total amount of cloud droplets as the risk probability corresponding to each preset risk level.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0030] During the construction of tunnel projects, the water-richness of the surrounding rock is one of the key factors affecting project safety and construction efficiency. Especially under karst geological conditions, water and mud gushing disasters have become one of the most serious disasters in tunnel construction, which not only causes huge economic losses, but may also cause serious casualties. A large number of engineering practices have shown that many tunnel safety accidents are caused by sudden geological disasters of mud and water gushing during construction, which pose a serious threat to the lives and safety of construction workers.

[0031] In order to prevent disasters caused by the high water content of the surrounding rock, it is necessary to predict the water content of the surrounding rock. The advanced geological prediction methods in related technologies include drilling, geological radar and transient electromagnetic method. Although these prediction methods can obtain water content information to a certain extent, their accuracy is low and it is difficult to meet the construction requirements under complex geological conditions.

[0032] An embodiment of the present invention provides an analysis method for the water-richness risk of surrounding rocks, which predicts the water-richness indexes of multiple target surrounding rocks to determine the water-richness risks of multiple target surrounding rocks, thereby achieving the effect of improving the accuracy of water-richness risk analysis.

[0033] According to an embodiment of the present invention, an embodiment of a method for analyzing the water-richness risk of surrounding rocks is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0034] In this embodiment, a method for analyzing the risk of water abundance of surrounding rocks is provided, which can be used in computer equipment. Figure 1 : is a flow chart of a method for analyzing surrounding rock water-richness risk according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0035] Step S101, querying a water-richness index adaptation table according to the resistivity corresponding to multiple surrounding rock samples of the tunnel, and obtaining first water-richness indexes corresponding to the multiple surrounding rock samples; wherein the water-richness index adaptation table includes correspondences between multiple resistivity ranges and multiple first water-richness indices.

[0036] Among them, multiple surrounding rock samples are multiple representative rock samples selected from the rocks around the tunnel in the tunnel project. The embodiment of the present invention obtains the resistivity of multiple surrounding rock samples according to the transient electromagnetic method, and uses a suitable transient electromagnetic instrument to detect the multiple surrounding rock samples to obtain the resistivity of the multiple surrounding rock samples.

[0037] In some optional embodiments, Table 1 illustrates a water-richness index adaptation table.

[0038] Table 1: Water richness index adaptation table.

[0039]

[0040]

[0041] For example, the resistivity of a surrounding rock sample is 750 ohm·m, which belongs to the resistivity range of 0-800 ohm·m, and the first water-richness index corresponding to the surrounding rock sample is 1.50.

[0042] Step S102, constructing a water-richness database of multiple surrounding rock samples according to the first water-richness indexes corresponding to the multiple surrounding rock samples; wherein the water-richness database is used to store the three-dimensional spatial coordinates of the multiple surrounding rock samples and the first water-richness indexes corresponding to the multiple surrounding rock samples.

[0043] In some optional embodiments, a water-richness database of multiple surrounding rock samples is constructed based on the first water-richness indexes corresponding to the multiple surrounding rock samples, including: obtaining the three-dimensional spatial coordinates of the multiple surrounding rock samples, associating the first water-richness index of each surrounding rock sample with the three-dimensional spatial coordinates to obtain an association result; and storing the association result to obtain a water-richness database.

[0044] Among them, the first water-richness index of each surrounding rock sample is aligned with the three-dimensional spatial coordinates. Specifically, the first water-richness index of each surrounding rock sample is accurately corresponded to its actual three-dimensional spatial position, so as to construct a water-richness database containing water-richness information and its spatial position.

[0045] In some optional embodiments, such as Figure 2 As shown, it is a schematic diagram of the distribution of the first water-rich index. First, the resistivity corresponding to multiple surrounding rock samples is obtained according to the transient electromagnetic method, and the water-rich index adaptation table is queried according to the resistivity to obtain the first water-rich index corresponding to the multiple surrounding rock samples. The darker the color, the larger the first water-rich index. Then, the first water-rich index of each surrounding rock sample is associated with the three-dimensional space coordinates to obtain the distribution of the first water-rich index in the three-dimensional space. Finally, the classification of the first water-rich index can be observed in the three-dimensional space. The darker the color, the higher the risk level corresponding to the first water-rich index.

[0046] Step S103, obtaining the surrounding rock point cloud model of the tunnel, predicting the second water-richness index of multiple target surrounding rocks in the surrounding rock point cloud model based on the water-richness database, and generating a target point cloud model containing the second water-richness index; wherein the surrounding rock point cloud model is used to characterize the geometric structure of the tunnel section.

[0047] The multiple target surrounding rocks are multiple surrounding rocks in the tunnel whose water-richness is to be predicted except for the surrounding rock samples.

[0048] In some optional embodiments, the coordinates of the point cloud data of the surrounding rock of the tunnel section are obtained by measuring technology, and a surrounding rock point cloud model is constructed according to the coordinates of the point cloud data of the surrounding rock of the tunnel section, wherein the measuring technology may be laser scanning.

[0049] In some optional embodiments, such as Figure 3 As shown in the figure, it is a schematic diagram of the surrounding rock point cloud model construction process. First, the coordinates of multiple point cloud data of the surrounding rock of the tunnel section are obtained. Figure 3In the figure, H is the tunnel height, D / 2 is the radius of the arc-shaped part of the tunnel section, and then, according to the first water-richness index, multiple point cloud data are classified into low risk, medium risk and high risk, respectively. Finally, a certain step length is assigned to multiple point cloud data to obtain a surrounding rock point cloud model. In the surrounding rock point cloud model, the risk levels of multiple surrounding rock samples can be distinguished by color.

[0050] In some optional embodiments, a K-nearest neighbor algorithm is used to predict the second water-richness index of multiple target surrounding rocks in the surrounding rock point cloud model. Specifically, the execution process of the K-nearest neighbor algorithm is: calculating the Euclidean distance between multiple first sample points of each surrounding rock sample and multiple second sample points of each target surrounding rock; based on the Euclidean distance, selecting multiple target first sample points closest to each second sample point as multiple neighbor points; and predicting the second water-richness index of multiple second sample points of the target surrounding rock based on the weighted average of the first water-richness index of multiple neighbor points of each second sample point.

[0051] Among them, the formula for calculating the Euclidean distance is:

[0052]

[0053] Where d(p,x) is the Euclidean distance between the first sample points and the second sample points, p x is the coordinate of the second sample point on the x-axis, x ix is the coordinate of the first sample point on the x-axis, p y is the coordinate of the second sample point on the y-axis, x iy is the coordinate of the first sample point on the y axis, p z is the coordinate of the second sample point on the z-axis, x iz is the coordinate of the i-th first sample point on the z-axis.

[0054] In some optional embodiments, the calculation formula of the second water-richness index is:

[0055]

[0056] Where W^ is the second water-richness index, K is the total number of target first sample points, and W i is the first sample point of the i-th target.

[0057] Step S104 , performing risk analysis on the target point cloud data in the target point cloud model according to the second water-richness indexes of the plurality of target surrounding rocks, to obtain risk levels corresponding to the target point cloud data.

[0058] In some optional implementations, a fuzzy cloud probability model is used to perform risk analysis on target point cloud data in the target point cloud model to obtain a risk level corresponding to the target point cloud data.

[0059] Specifically, the process of performing risk analysis on the target point cloud data in the target point cloud model using the fuzzy cloud probability model is as follows: determining the characteristic parameters of the fuzzy cloud model according to the second water-richness index of multiple target surrounding rocks; wherein the fuzzy cloud model is a model used for uncertainty analysis; simulating the cloud droplet generation process according to the characteristic parameters, and counting the number of cloud droplets to obtain the number of cloud droplets corresponding to multiple preset risk levels; generating the risk probability corresponding to each preset risk level according to the number of cloud droplets corresponding to multiple preset risk levels; and determining the preset risk level with the highest risk probability as the risk level corresponding to the target point cloud data.

[0060] Among them, the characteristic parameters of the fuzzy cloud model include expected Ex, entropy En and super entropy He. The calculation formula of expected Ex is:

[0061]

[0062] Where Ex is the expectation, q is the total number of the second water-richness index, and x i is the i-th second water-richness index.

[0063] The calculation formula of entropy En is:

[0064]

[0065] Where En is entropy, q is the total number of the second water-richness index, and x i is the i-th second water-richness index, and Ex is the expectation.

[0066] The calculation formula of excess entropy He is:

[0067]

[0068] Among them, Ex is the super entropy, S 2 is the variance of the second water-richness index, and En is the entropy.

[0069] Among them, the variance S 2 The calculation formula is:

[0070]

[0071] Among them, S 2 is the variance, q is the total number of the second water-richness index, x i is the i-th second water-richness index, and Ex is the expectation.

[0072] In some optional implementations, the cloud droplet generation process is simulated according to the characteristic parameters by means of a membership function. In the embodiment of the present invention, a deviation function is used instead of a membership function. The formula of the deviation function is:

[0073]

[0074] Among them, Z n is the deviation function, Enn is the entropy En as the expectation and the super entropy Ex as the 2 Normally distributed random numbers generated for the load variance, x n To expect Ex as the expectation, to expect Enn 2 A random number generated from a normal distribution with variance x i is the i-th second water-richness index.

[0075] In some optional implementations, Table 2 illustrates the correspondence between multiple preset risk levels and water richness index ranges.

[0076] Table 2: Correspondence between multiple preset risk levels and water richness index ranges.

[0077] Risk Level Risk Statement Water richness index range Risk Control Measures I Low risk <0.1 Routine monitoring, drainage maintenance II Medium risk 0.1-0.5 Pre-drainage, waterproof wall installation, enhanced monitoring III High risk >0.5 Stop construction, force drainage, and reinforce rock formations

[0078] In some optional implementations, the membership function formula is:

[0079]

[0080] Among them, f1 is the membership function of the low-risk area, and x is the second water-richness index.

[0081]

[0082] Among them, f2 is the membership function of the medium-risk area, and x is the second water-richness index.

[0083]

[0084] Among them, f3 is the membership function of the high-risk area, and x is the second water-richness index.

[0085] In some optional implementations, according to the number of cloud droplets corresponding to multiple preset risk levels, a formula for generating the risk probability corresponding to each preset risk level is:

[0086]

[0087] Among them, P i is the probability corresponding to the i-th preset risk level, N i is the number of cloud droplets corresponding to the i-th preset risk level, N1 is the number of cloud droplets corresponding to the low preset risk level, N2 is the number of cloud droplets corresponding to the medium preset risk level, N3 is the number of cloud droplets corresponding to the high preset risk level, and N1+N2+N3 is the total number of cloud droplets.

[0088] Exemplarily, the probability corresponding to the low preset risk level is 0.1, the probability corresponding to the medium preset risk level is 0.2, and the probability corresponding to the high preset risk level is 0.5, and the risk level corresponding to the target point cloud data is a high risk level.

[0089] In some optional implementations, in addition to using the fuzzy cloud probability model, the risk level corresponding to the target point cloud data may also be determined by using a threshold division method, a statistical analysis method, and a neural network model.

[0090] Among them, the steps of the threshold division method are: obtaining the corresponding relationship between the preset interval of the preset water-richness index and the risk degree, matching the second water-richness index of multiple target surrounding rocks with the preset interval, and determining the risk degree corresponding to the successfully matched target preset interval as the risk level corresponding to the target point cloud data.

[0091] The steps of the statistical analysis method are: statistically analyze the second water-richness index of all target surrounding rocks, calculate its mean, standard deviation and other statistical quantities, and divide the risk level according to the statistical results; among them, the mean can reflect the overall water-richness level, and the standard deviation can reflect the degree of dispersion of the water-richness index. The greater the dispersion, the higher the uncertainty of the water-richness, and the possible risk is relatively large. The area where the second water-richness index is lower than the mean minus a certain multiple (for example, 2 times) of the standard deviation is divided into a low risk level, the area higher than the mean plus a certain multiple of the standard deviation is divided into a high risk level, and the middle part is a medium risk level.

[0092] The steps of using the neural network model to determine the risk level corresponding to the target point cloud data are as follows: obtaining a large amount of surrounding rock sample data with known risk level annotations, using the surrounding rock sample data to train the neural network model, inputting the second water-richness index of multiple target surrounding rocks into the trained neural network model, and obtaining the risk level corresponding to the target point cloud data.

[0093] The analysis method of surrounding rock water-richness risk provided in this embodiment queries the first water-richness index corresponding to multiple surrounding rock samples through the water-richness index adaptation table, and constructs a water-richness database of multiple surrounding rock samples according to the first water-richness index corresponding to multiple surrounding rock samples. The embodiment of the present invention stores the first water-richness index corresponding to multiple surrounding rock samples and their three-dimensional spatial coordinates in the water-richness database, providing a comprehensive and orderly data basis for subsequent prediction and analysis. The embodiment of the present invention uses the constructed water-richness database to predict the second water-richness index of multiple target surrounding rocks to be predicted for water-richness other than the surrounding rock samples, which can more accurately reflect the water-richness of the target surrounding rocks and provide a more reliable basis for engineering decision-making. The embodiment of the present invention performs risk analysis on the target point cloud data in the target point cloud model according to the second water-richness index of multiple target surrounding rocks, obtains the risk level corresponding to the target point cloud data, and converts complex geological information into intuitive risk levels, so that engineering personnel can clearly understand the degree of water-richness risk of different parts of the tunnel, so as to take corresponding prevention and response measures in a targeted manner to reduce engineering risks and costs. Compared with the related art, the embodiment of the present invention predicts the water-richness index of multiple target surrounding rocks to determine the water-richness risks of multiple target surrounding rocks, thereby improving the accuracy of water-richness risk analysis, being more suitable for construction requirements under complex geological conditions, and improving the safety of tunnel engineering construction.

[0094] In this embodiment, a method for analyzing the risk of water abundance of surrounding rocks is provided, which can be used in computer equipment. Figure 4 FIG. 4 is a flow chart of another method for analyzing the risk of surrounding rock water abundance according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0095] Step S401, querying a water-richness index adaptation table according to the resistivity corresponding to multiple surrounding rock samples of the tunnel, and obtaining first water-richness indexes corresponding to the multiple surrounding rock samples; wherein the water-richness index adaptation table includes correspondences between multiple resistivity ranges and multiple first water-richness indices.

[0096] In some optional implementations, the above step S401 includes:

[0097] Step S4011, querying a water-richness index adaptation table according to the resistivities corresponding to a plurality of surrounding rock samples of the tunnel, and obtaining a target resistivity range of the resistivity corresponding to each surrounding rock sample.

[0098] Among them, the embodiment of the present invention obtains the resistivity of multiple surrounding rock samples according to the transient electromagnetic method, and uses a suitable transient electromagnetic instrument to detect the multiple surrounding rock samples to obtain the resistivity of the multiple surrounding rock samples.

[0099] In some optional embodiments, the water richness index adaptation table includes a correspondence between a plurality of resistivity ranges and a plurality of first water richness indices.

[0100] Step S4012, determining a first water-richness index corresponding to the target resistivity range.

[0101] Among them, the water-richness index corresponding to the target resistivity range is determined as the first water-richness index.

[0102] Step S402, constructing a water-richness database of multiple surrounding rock samples according to the first water-richness indexes corresponding to the multiple surrounding rock samples; wherein the water-richness database is used to store the three-dimensional spatial coordinates of the multiple surrounding rock samples and the first water-richness indexes corresponding to the multiple surrounding rock samples.

[0103] In some optional implementations, the above step S402 includes:

[0104] Step S4021, obtaining the three-dimensional spatial coordinates of multiple surrounding rock samples, and associating the first water-richness index of each surrounding rock sample with the three-dimensional spatial coordinates to obtain an association result.

[0105] Among them, the first water-richness index of each surrounding rock sample is aligned with the three-dimensional spatial coordinates. Specifically, the first water-richness index of each surrounding rock sample is accurately corresponded to its actual three-dimensional spatial position, so as to construct a water-richness database containing water-richness information and its spatial position.

[0106] Step S4022, storing the association results to obtain a water-richness database.

[0107] The embodiment of the present invention achieves the organic integration of the water-richness index and the spatial position information by acquiring the three-dimensional spatial coordinates of multiple surrounding rock samples and associating them with the first water-richness index. After associating the water-richness index with the three-dimensional spatial coordinates, the spatial distribution of the water-richness of each surrounding rock sample can be accurately located. This helps to understand the spatial variation law of the water-richness of the tunnel surrounding rock in more detail and provides an accurate basis for targeted treatment of different locations in the project.

[0108] Step S403, obtaining the surrounding rock point cloud model of the tunnel, predicting the second water-richness index of multiple target surrounding rocks in the surrounding rock point cloud model based on the water-richness database, and generating a target point cloud model containing the second water-richness index; wherein the surrounding rock point cloud model is used to characterize the geometric structure of the tunnel section.

[0109] In some optional implementations, the above step S403 includes:

[0116] Step S4042, simulating the cloud droplet generation process according to the characteristic parameters, and counting the number of cloud droplets to obtain the number of cloud droplets corresponding to multiple preset risk levels.

[0117] In some optional embodiments, such as Figure 5 As shown in the figure, it is a schematic diagram of cloud droplet distribution. According to the second water-richness index of multiple target surrounding rocks, the characteristic parameters of the fuzzy cloud model are determined. For example, the characteristic parameter expectation Ex is 0.5, the entropy En is 0.1, the excess entropy He is 0.03, and the total number of cloud droplets N is 5000. Figure 6 As shown, this is a schematic diagram of risk level classification of the fuzzy cloud probability model. By dividing the risk levels in the fuzzy cloud probability model, three preset risk levels are obtained, namely high risk, medium risk and low risk. By observing the cloud droplet distribution in the fuzzy cloud probability model, the number of cloud droplets in different preset risk levels can be obtained.

[0122] In some optional embodiments, such as Figure 7 As shown, it is a schematic diagram of the risk level in the surrounding rock point cloud model of the tunnel. After obtaining the risk levels corresponding to different target surrounding rocks, the risk levels are distinguished by color depth in the surrounding rock point cloud model. The darker the color, the higher the risk level. Through the visualization of risk levels, the water-rich risk level of the surrounding rock of the tunnel section can be directly observed.

[0123] The analysis method of surrounding rock water-rich risk provided by this embodiment determines the characteristic parameters of the fuzzy cloud model according to the second water-rich index of multiple target surrounding rocks, uses the fuzzy cloud model to perform uncertainty analysis, fully considers the complexity and uncertainty factors of the geological environment, and can more truly reflect the actual situation of the surrounding rock water-rich risk, thereby improving the accuracy of subsequent water-rich risk analysis. The present invention simulates the cloud droplet generation process and counts the number according to the characteristic parameters, and then determines the risk probability corresponding to each preset risk level, avoiding the arbitrariness of subjective judgment, making the determination of the risk level more accurate and reliable.

[0126] The first water-richness index is registered in three-dimensional space to construct a water-richness database.

[0127] Based on the water-richness database, the second water-richness index of multiple target surrounding rocks in the surrounding rock point cloud model is predicted by the K nearest neighbor algorithm to obtain the target point cloud model.

[0128] Through the fuzzy cloud probability algorithm, the risk probability corresponding to each preset risk level is quantified, and the risk level is determined based on the risk probability.
