Technical Field

[0001] The present invention belongs to the technical field of geological disaster risk assessment, and in particular relates to a geological disaster risk assessment method and system based on slope units. Background Art

[0002] Geological hazard assessment is to investigate, monitor, analyze and evaluate the activity level of possible geological disasters such as collapse, landslide, mud-rock flow, etc., aiming to determine the destructive capacity of geological disasters and provide a scientific basis for geological disaster prevention and control. Geological hazard assessment is a vital task, which deeply analyzes the potential conditions, triggering factors and possible impact range of geological disasters. Through this assessment, we can not only predict the severity and frequency of geological disasters, but also provide strong support for the formulation of effective disaster prevention and mitigation measures. During the assessment process, the expert team will conduct a comprehensive analysis of possible geological disasters based on multiple factors such as geological environment, climatic conditions, and human activities. Using advanced monitoring technology and data analysis methods, the potential danger points of geological disasters can be more accurately identified, and their possible social, economic and environmental impacts can be assessed.

[0003] In order to conduct geological hazard assessment more reasonably and conveniently, various regions have carried out slope geological hazard risk detailed investigation technology projects, and through this project, corresponding geological hazard hazard assessment methods based on slope units have been formulated to conduct risk assessment. However, in actual use, although the existing assessment methods can achieve the purpose of risk assessment, they still generally have the following problems: Imperfection of the assessment model: Most of the existing geological hazard assessment models are based on historical data and empirical formulas, which cannot fully reflect the complexity and uncertainty of geological hazards. At the same time, the selection and setting of model parameters are also subjective and uncertain, which will affect the reliability of the assessment results.

[0004] Failure to fully consider the coupling of multiple factors: The occurrence of geological disasters is often affected by multiple factors, including geological conditions, climate conditions, human activities, etc. However, the current assessment method does not fully consider the coupling of these factors, which will lead to incomplete and inaccurate assessment results. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a method and system for assessing the risk of geological hazards based on slope units, which has the advantages of a complete assessment model and fully considers the coupling effect of multiple factors. It solves the problem that the assessment model of the existing method and system for assessing the risk of geological hazards based on slope units is imperfect, which affects the reliability of the assessment results, and does not fully consider the coupling effect of multiple factors, which leads to the problem that the assessment results are not comprehensive and accurate enough.

[0021] refer to Figure 2 , the step 1 comprises S11. Review geological survey reports, geological environment monitoring data, and historical geological disaster records to understand the geological structure, topography, lithology, and strata, and collect geological environmental conditions for the formation of geological disasters.

[0022] When implementing the method, it is necessary to conduct in-depth analysis of geological survey reports, environmental monitoring data, and historical geological disaster records to obtain detailed and accurate information about geological structure, topography, lithology, and stratigraphic conditions. Subsequently, combined with meteorological data and human activity data, scientific analysis methods are used to reveal the inducing factors and deep-seated causes of geological disasters. In this process, it is crucial to sort out the historical records and prevention and control measures of geological disasters, which provide a solid foundation for accurately identifying the types and levels of disasters. At the same time, by comprehensively evaluating the socioeconomic conditions of the affected areas, this workflow can more accurately predict the possible impact of geological disasters on the socioeconomic situation. Finally, by establishing a geological disaster prevention and control database and conducting in-depth statistical analysis, this workflow can extract key information from massive data and reveal the main laws and characteristics of geological disasters. These laws and characteristics are of great significance for formulating targeted geological disaster prevention and control measures.

[0023] By deeply understanding the geological background and inducing factors of geological disasters, we can more accurately identify the types and occurrence areas of potential geological disasters, providing strong support for the prevention and response of geological disasters. Secondly, a comprehensive assessment of the social and economic conditions in the disaster-stricken areas will help to more accurately grasp the actual impact of geological disasters on the social economy, and provide an important basis for the formulation of scientific and reasonable prevention and control strategies. In addition, the establishment and statistical analysis of the geological disaster prevention and control database will help to better grasp the main laws and characteristics of geological disasters, and provide a scientific basis for the formulation of accurate and effective prevention and control measures.

[0025] When implementing the method, it is necessary to accurately locate the specific location and range of the slope unit, and use advanced geographic information technology to collect detailed geographical and geological background data. These data provide a solid foundation for in-depth understanding of the geological characteristics of the slope unit. Subsequently, the InSAR observation equipment, airborne laser radar system and drone photogrammetry equipment were carefully inspected and strictly calibrated to ensure that they can operate with the highest accuracy and stability. In the data acquisition stage, the high resolution and continuity advantages of InSAR observation technology were fully utilized to monitor the surface deformation of the slope unit around the clock and without interruption. At the same time, the airborne laser radar system captured the subtle terrain changes of the slope unit with its efficient three-dimensional terrain scanning capability. UAV photogrammetry provides multi-angle and high-definition images of the slope unit with its flexibility and high-resolution imaging capabilities. In the data processing stage, advanced algorithms and technical means were used to perform complex processing such as phase unwrapping and filtering on the InSAR observation data to extract accurate surface deformation information. For the airborne laser radar measurement data, point cloud processing technology and three-dimensional modeling software were used to generate a detailed three-dimensional terrain model of the slope unit. As for the drone photogrammetry data, intuitive and easy-to-understand two-dimensional images of the slope units are generated through image stitching, feature extraction and other steps.

Secondly, the use of new technologies and methods to identify geological disaster risk sources can improve the accuracy and efficiency of identification and reduce the risk of disasters. In addition, by comparing and verifying the results of identification with new technologies and methods and the results of field investigations, we can evaluate the applicability and characteristics of new technologies and provide technical support for geological disaster prevention and control.

Comprehensively analyze and interpret the data obtained from geophysical exploration and drilling, extract key information, and combine ground survey data to conduct a comprehensive assessment of the geological structure, groundwater characteristics, and landslide stability of the slope. Based on the assessment results, determine the hazard level of geological hazards and potential risk areas.

[0031] When implementing the method, it is necessary to systematically organize the data and information obtained from the ground survey and clarify the geological problems and goals to be solved. Then, based on these results, determine the preliminary work area and focus of geophysical exploration and drilling, and then prepare the required equipment and tools. In the geophysical exploration stage, according to the geological characteristics and detection needs of the slope, select the appropriate geophysical exploration method, arrange the survey line, set the detection points and depth, and conduct on-site data collection.

Finally, based on the comprehensive geological information, conduct a quantitative assessment of the risk of geological hazards, determine the risk level, and propose targeted prevention and control measures and suggestions.

[0034] When implementing the method, it is necessary to carry out field surveys in the target mountains, systematically collect basic data such as topography, vegetation coverage and water system distribution, accurately identify potential geological disaster sources, and preliminarily define their scale and boundary range. Subsequently, according to the characteristics of the terrain, measurement control points are set at key points, and precise topographic survey operations are carried out using total stations and RTK equipment to ensure that the acquired terrain data are detailed and accurate. On this basis, a topographic map is drawn in combination with the terrain characteristics, and the specific location and coverage of the disaster risk source are clearly marked. Next, for the disaster risk source area, the engineering geological profile line is reasonably arranged to ensure that the direction of the profile line is perpendicular to the main sliding direction of the geological disaster. Subsequently, standardized excavation operations are carried out along the profile line to fully expose the geological structural characteristics of the soil and rock layers. After the excavation is completed, the engineering geological profile is carefully measured, and the observed geological disaster characteristics are recorded in detail, supplemented by taking photos and videos to ensure that the data are fully archived. Finally, the topographic survey data and the engineering geological profile measurement data are integrated to construct a comprehensive and accurate three-dimensional geological model. Through in-depth analysis of the model, the material composition, formation conditions and vertical engineering geological structure of geological hazard sources are revealed. Based on these comprehensive geological information, an objective and scientific quantitative assessment of the danger of geological hazards is carried out, and the corresponding danger level is determined accordingly, and practical prevention and control measures and suggestions are proposed.

[0035] Through rigorous field investigation and high-precision topographic survey, the topographic and geomorphic characteristics of the target mountain and the status of geological disaster risk sources can be fully and systematically grasped. With the help of the layout and excavation measurement of engineering geological profile lines, the geological structure of soil and rock layers can be revealed intuitively and accurately, providing solid data support for in-depth research on geological disasters. By constructing a three-dimensional geological model and conducting comprehensive geological information analysis, it is possible to accurately assess the risk of geological disasters and provide a scientific basis for the formulation of targeted prevention and control measures.

At the same time, mechanical properties such as compressive strength, tensile strength, and shear strength are tested on the samples to comprehensively evaluate the mechanical properties of the samples. In the data processing and analysis stage, attention is paid to the accuracy and reliability of the data. Through detailed recording, collation, and analysis, the physical and mechanical parameters required for stability evaluation are extracted. Statistical methods and professional software are used to process the data to further improve the accuracy and reliability of the parameters. Finally, the extracted physical and mechanical parameters are verified to ensure that they are suitable for geological hazard assessment.

[0040] Working principle of the present invention: The implementation of geological hazard assessment work must first collect various types of geological hazard-related information extensively, and systematically organize and analyze them to lay a solid foundation for subsequent assessment work. Subsequently, with the help of advanced InSAR observation technology, airborne lidar measurement and drone photogrammetry technology, accurate identification and dynamic monitoring of slope units can be achieved. At the same time, ground investigators go deep into the site to carefully survey the geological conditions and potential sources of hazards that may cause disasters, and fully understand the actual situation of geological disasters. On this basis, through geophysical exploration and drilling technology, the internal structure of the slope and the characteristics of landslides are further revealed, and the inherent laws and mechanisms of geological disasters are mastered. Mountain engineering and engineering geological profile measurement work can more finely depict the scale, form and boundaries of geological hazard sources, and provide more detailed geological information for the assessment work.
