Description

Technical Field

[0001] The present invention relates to the technical field of disaster prevention and control, and particularly to an active protection system for geological disaster prevention and control. Background Art

[0002] Geological disasters refer to geological processes or phenomena formed under the action of natural or human factors that cause losses to human life and property and damage to the environment. The distribution and variation laws of geological disasters in time and space are not only restricted by the natural environment but also related to human activities. They are often the result of the interaction between humans and nature. The basic environment and overall conditions that control and influence the formation and development of geological disasters are both closely related to and somewhat different from the formation conditions of geological disasters. The formation conditions of geological disasters refer to the direct factors that cause geological disasters; the geological disaster background refers to the higher-level basic conditions that control and influence geological disasters; When the common active protection systems for geological disaster prevention and control are in use, there is blindness in allocating protection resources, and there is a lack of targeted design to improve the buffering capacity, and it is impossible to comprehensively prevent and control various possible geological disasters. For this reason, we propose an active protection system for geological disaster prevention and control. Summary of the Invention

The user uses the drawing unit to determine the range of the collected geological information and obtain the drawn geological information; The case extraction module collects the locations where geological disasters have occurred in the past and analyzes the geological information at these locations to obtain past cases; The case matching module extracts the geological features in the drawn geological information and past cases to obtain the drawn features and case features, then matches the case features with the same features as the drawn features, and extracts the corresponding past cases, and analyzes the geological disaster information that occurred in the past cases to obtain a geological disaster table; The combined layout module extracts pre-occurring disasters, calculates the probabilities of different pre-occurring disasters, sorts them, obtains a disaster probability table, analyzes the protection methods for pre-occurring disasters, then splits the protection methods to obtain implementation projects, analyzes and marks the positions of the protection methods in the circled geological information to obtain protection areas, splits the protection areas into X protection sub-areas, splits the protection sub-areas again to obtain Y engineering sub-domains, extracts the implementation projects corresponding to the first disaster in the disaster probability table, and arranges them at the middle position of the engineering sub-domains, and arranges the implementation projects corresponding to the second disaster and the third disaster in sequence below and above the adjacent middle engineering sub-domains. Arrange the implementation projects corresponding to the disasters in the disaster probability table into all the engineering sub-domains according to the above method to obtain a comprehensive protection plan; The effect analysis module uses LPF3D to build a three-dimensional geological model for the circled geological information, arranges the comprehensive protection plan into the three-dimensional geological model, simulates different geological disasters in sequence according to the order of the disaster probability table in the three-dimensional geological model, and analyzes the effects of the comprehensive protection plan in the face of different geological disasters to obtain protection effects.

[0005] As a further solution of the present invention: After the circled geological information in the data acquisition module is obtained, a verification unit will be established synchronously. The user puts forward geological information different from the circled geological information through the verification unit, and uses a drone to obtain high-resolution geological images and three-dimensional data at low altitude to obtain verification information, and then uses the verification information to verify and improve the authenticity of the circled geological information.

Let the case features with the same features as the circled features be : Calculate the case features that have the same features as the circled features according to the above formula to obtain the information of cases with the same features.

[0009] As a further solution of the present invention: After obtaining the information of cases with the same features in the case matching module, it will analyze the number of the same features between the case features different from the previous cases and the circled features, so as to obtain the number of the same features. At this time, it will synchronously analyze the number of the circled features to obtain the number of basic features, and then calculate the feature index of the previous cases. Let the number of the same features be Let the number of basic features be Let the feature index of the previous cases be : Calculate the feature index of the previous cases according to the above formula, and then sort the previous cases according to the size of the feature index. The sorting rule is in descending order.

When the superimposed probability is greater than or equal to the superimposed threshold, it will synchronously analyze the sorting of the pre-emerging disasters corresponding to different execution projects in the disaster probability table, and obtain the first project and the second project according to the size. Then, circle the pre-emerging disasters corresponding to the second project in the disaster probability table, and arrange the second project into the engineering sub-domain where the first project is arranged. At the same time, after arranging a protection sub-region, when the superimposed probability is less than the superimposed threshold, it will be independently arranged, and the remaining protection sub-regions will be arranged based on the arranged protection sub-region.

[0012] As a further solution of the present invention: After obtaining the protection effect in the effect analysis module, it will use GeoStudio to evaluate the protection effect to obtain the effect value, and then establish an effect threshold. When the effect value is greater than or equal to the effect threshold, the corresponding comprehensive protection plan will be output and displayed.

[0015] The following further describes the specific embodiments of the present invention in conjunction with the drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not limit the present invention.

[0016] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] Please refer to the attached Figure 1 , an active protection system for geological disaster prevention and control of the present invention includes a data acquisition module, a case extraction module, a case matching module, a combined layout module, and an effect analysis module; The data acquisition module is used to collect geological information, and a circled unit is established. The user uses the circled unit to determine the scope of the collected geological information and obtains the circled geological information; The case extraction module collects the locations where geological disasters have occurred in the past and analyzes the geological information at these locations to obtain previous cases; The case matching module extracts the circled geological information and the geological features in previous cases to obtain the circled features and case features. Then, it matches the case features with the same features as the circled features, extracts the corresponding previous cases, analyzes the geological disaster information that occurred in the previous cases, and obtains a geological disaster table. The combined layout module extracts the predicted disasters, calculates the probabilities of different predicted disasters occurring, and sorts them to obtain a disaster probability table. It analyzes the protection methods for dealing with the predicted disasters, then splits the protection methods to obtain the implementation projects, analyzes the positions where the protection methods are arranged in the circled geological information to obtain the protection areas, splits the protection areas into X protection sub-areas, and splits the protection sub-areas again to obtain Y engineering sub-domains. It extracts the implementation project corresponding to the first disaster in the disaster probability table and arranges it in the middle position of the engineering sub-domain, and arranges the implementation project corresponding to the second disaster and the implementation project corresponding to the third disaster in the lower and upper positions adjacent to the middle engineering sub-domain in turn. According to the above method, the implementation projects corresponding to the disasters in the disaster probability table are arranged in all the engineering sub-domains to obtain a comprehensive protection plan. At the same time, it is also possible to summarize the scope of the protection area, and then calculate the scope of arranging different implementation projects in the protection area according to the probabilities of different geological disasters occurring in the disaster probability table, so that the implementation projects of the geological disasters that are more likely to occur can occupy more space, enabling more corresponding implementation projects to be arranged. The effect analysis module uses LPF3D to build a three-dimensional geological model for the circled geological information, arranges the comprehensive protection plan into the three-dimensional geological model, sequentially simulates different geological disasters in the three-dimensional geological model according to the order of the disaster probability table, and analyzes the effects of the comprehensive protection plan in the face of different geological disasters to obtain the protection effects.

[0018] In an embodiment of the present invention: After the circled geological information in the data acquisition module is obtained, a verification unit is established synchronously. The user puts forward geological information different from the circled geological information through the verification unit, and uses a drone to obtain high-resolution geological images and three-dimensional data at low altitude to obtain verification information, and then uses the verification information to verify and improve the authenticity of the circled geological information.

[0019] In an embodiment of the present invention: When the previous cases in the case extraction module are obtained, a distance retrieval unit is established, and the distances between different previous cases and the circled geological information are retrieved, and then the previous cases are sorted from near to far.

[0020] In an embodiment of the present invention: After the geological disaster table in the case matching module is obtained, weather information is collected to further filter the geological disaster table, so as to further screen the predicted disasters.

[0021] In an embodiment of the present invention: When the case matching module matches the case features with the same features as the circled features, let the circled features be , , , ……, , and let the case features be , , , ……, , where T and R are the numbers of the circled features and the case features respectively. Let the case features with the same features as the circled features be : Calculate the case features with the same features as the circled features according to the above formula to obtain the case information with the same features.

[0022] In an embodiment of the present invention: After the case information with the same features is obtained in the case matching module, it will analyze the number of the same features between the case features of different previous cases and the circled features, so as to obtain the number of the same features. At this time, it will synchronously analyze the number of the circled features to obtain the number of basic features, and then calculate the feature index of the previous cases. Let the number of the same features be , let the number of basic features be , and let the feature index of the previous cases be : Calculate the feature index of the previous cases according to the above formula, and then sort the previous cases according to the size of the feature index. The sorting rule is in descending order.

[0023] In an embodiment of the present invention: When the protection sub-region and the engineering sub-domain in the combined layout module are obtained, a quantity editing unit will be established, and the user can control the quantity of the split protection sub-regions and the quantity of the engineering sub-domains through the quantity editing unit.

[0024] In an embodiment of the present invention: After the comprehensive protection plan in the combined layout module is obtained, it will analyze the possibility of superimposed layout of different execution projects in an engineering sub-domain to obtain the superimposed probability, and establish a superimposed threshold. When the superimposed probability the superimposed threshold, it will synchronously analyze the sorting of the predicted disasters corresponding to different execution projects in the disaster probability table, and obtain the first project and the second project according to the size. Then, circle the predicted disasters corresponding to the second project in the disaster probability table, and arrange the second project into the engineering sub-domain where the first project is arranged. At the same time, after the layout of a protection sub-region is completed, when the superimposed probability the superimposed threshold, it will be independently arranged, and the remaining protection sub-regions will be arranged based on the completed protection sub-region.

[0025] The user has the permission to edit the overlay threshold, which can be changed according to the user's needs. The overlay probability can be analyzed by whether the positions of the two execution projects conflict with each other and whether the layout floor heights are the same during layout, or it can also be analyzed by ABAQUS. ABAQUS is a powerful general finite element analysis software that can accurately simulate various complex engineering structures and mechanical problems. When analyzing the overlay placement of geological disaster protection devices, it can model the structure of the protection devices, considering factors such as material properties, geometric parameters, and boundary conditions, and evaluate whether the overlay placement will cause problems such as structural failure and stress concentration by simulating the stress conditions under different working conditions, such as seismic forces and geotechnical pressures, so as to judge its feasibility.

[0026] In one embodiment of the present invention: after the protection effect in the effect analysis module is obtained, GeoStudio is used to evaluate the protection effect to obtain the effect value, and then an effect threshold is established. When the effect value is less than or equal to the effect threshold, the corresponding comprehensive protection plan is output and displayed. When the effect value is greater than the effect threshold, a signal for regenerating the comprehensive protection plan is transmitted to the combined layout module.

Analyze the protection methods for pre-occurring disasters, then split the protection methods, analyze the positions of the protection methods in the circled geological information to obtain the protection area, split the protection area into X protection sub-areas, and split the protection sub-areas again to obtain Y engineering sub-domains. Extract the execution project corresponding to the first disaster in the disaster probability table and arrange it in the middle position of the engineering sub-domain, and arrange the execution projects corresponding to the second disaster and the third disaster in the lower and upper positions adjacent to the middle engineering sub-domain in turn. Arrange the execution projects corresponding to the disasters in the disaster probability table into all the engineering sub-domains according to the above method, build a three-dimensional geological model for the circled geological information using LPF3D, and arrange the comprehensive protection plan into the three-dimensional geological model to analyze the effect of the comprehensive protection plan in the face of different geological disasters.

[0028] Example 2. Please refer to the appendix Figure 1, collect geological information, obtain the delineated geological information, propose geological information different from the delineated geological information through the verification unit, and use the drone to obtain high-resolution geological images and three-dimensional data at low altitude. Use the verification information to verify and improve the authenticity of the delineated geological information, obtain past cases, retrieve the distances between different past cases and the delineated geological information, and then sort the past cases from near to far.

At this time, synchronously analyze the number of delineated features to obtain the number of basic features, and then calculate the feature index of the past cases.

[0029] Embodiment 3.

When different execution projects can be superimposed and arranged in one engineering sub-domain, synchronously analyze the sorting of the predicted disasters corresponding to different execution projects in the disaster probability table, and obtain the first project and the second project according to the size. Then circle the predicted disasters corresponding to the second project in the disaster probability table, and arrange the second project into the engineering sub-domain where the first project is arranged. At the same time, after arranging one protection sub-area, when it cannot be superimposed and arranged, it will be arranged independently, and the remaining protection sub-areas will be arranged based on the arranged protection sub-area. Use GeoStudio to evaluate the protection effect, so as to obtain the effect value, and analyze the relationship between the effect value and the effect threshold, and perform different operations according to different relationships.

[0030] Specifically, LPF3D builds a bridge for the conversion and coupling between multiple algorithms such as Smoothed Particle Hydrodynamics (SPH), Finite Element Method (FEM), Discrete Element Method (DEM), and Finite Volume Method (FVM), and establishes a new numerical simulation method for solving the multi-phase and multi-medium coupling calculation of landslide solid-particle-fluid, which can realize the full three-dimensional calculation under multi-phase material coupling, multi-state material transformation, and complex dynamic effects. It is mainly used for the visualization, high efficiency, and high precision solution of high-level rockfalls, debris flows, mudslides, mudflows, and composite geological disasters, providing support for the quantitative assessment of disaster prevention and mitigation of high-level long-distance geological disasters.

[0031] Specifically, GeoStudio is a software package specially used for geotechnical engineering and geological environment simulation analysis. It contains multiple modules that can simulate different geological problems respectively. It can take into account the heterogeneity and anisotropy of geological materials, as well as the coupling of multiple factors such as groundwater seepage and soil mechanics. It can be used to simulate geological disaster scenarios such as slope stability, groundwater flow, soil liquefaction, etc., and evaluate the effectiveness of corresponding protection plans such as slope reinforcement and drainage system design.

[0032] Specifically, fuzzy mathematical theory is used to perform fuzzy matching on circle features and case features, and the similarity measure between features is calculated. This can not only find cases with exactly the same features, but also find cases with a high degree of similarity, providing more possible references for geological disaster prediction. Intelligent optimization algorithms such as genetic algorithms and particle swarm optimization algorithms are used to optimize the layout of protection projects. Under the premise of meeting the protection effect, the protection cost is reduced and the resource utilization efficiency is improved. For example, the optimization algorithm is used to determine the best division method of protection sub-areas and engineering sub-areas, as well as the optimal layout location of the execution project. Working principle: First, geological information is collected to obtain circled geological information. Geological information different from the circled geological information is proposed through the verification unit, high-resolution geological images and three-dimensional data are obtained, the authenticity of the circled geological information is verified and improved, previous cases are obtained, the distances between different previous cases and the circled geological information are retrieved, and then the previous cases are sorted from near to far, the geological features in the circled geological information and previous cases are extracted, the geological disaster information appearing in the previous cases is analyzed, and a geological disaster table is obtained. Weather information is collected, and the geological disaster table is further filtered, and case features that have the same features as the circled features are calculated, and the number of case features of different previous cases that have the same features as the circled features is analyzed, so as to obtain the number of same features, and the number of circled features and the number of basic features are simultaneously analyzed, and then the feature index of the previous cases is calculated, and the previous cases are sorted according to the size of the feature index. Sorting process, the sorting rule is descending, calculate the probability of occurrence of different predicted disasters, analyze the protection methods for predicted disasters, split the protection methods, obtain the execution project, split the protection area into X protection sub-areas, split the protection sub-areas again, obtain Y engineering sub-domains, and regularly arrange the execution projects in the engineering sub-domains. The number of split protection sub-areas and engineering sub-domains are controlled by the quantity editing unit. It will analyze whether different execution projects can be superimposed in one engineering sub-domain, and superimpose the engineering sub-domains that can be superimposed into one engineering sub-domain. Use LPF3D to build a three-dimensional geological model for the circled geological information, use GeoStudio to evaluate the protection effect, so as to obtain the effect value, and analyze the relationship between the effect value and the effect threshold. Perform different operations according to the different relationships. At this point, the entire workflow ends.

[0033] Although the present invention is disclosed above in preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, all modifications, equivalent changes and decorations made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention fall within the protection scope defined by the claims of the present invention.
