Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of mountain landslide disaster early warning, and in particular to a mountain landslide disaster early warning method and system. Background Art
[0002] At present, the traditional early warning scheme for mountain landslide disasters is to first predict mountain landslide disasters and then issue mountain landslide disaster early warnings based on the prediction results. The traditional mountain landslide disaster prediction scheme is generally as follows:
[0003] 1. Geological Survey and Analysis
[0004] Geological survey and analysis are fundamental to landslide disaster prediction. Detailed investigation of factors such as the geological structure, stratum lithology, geological structure, and groundwater distribution in a potential landslide area can determine the geological background and potential sliding surface. Furthermore, historical landslide events must be analyzed to identify their occurrence patterns and provide foundational data for prediction.
[0005] 2. Application of monitoring instruments
[0006] Monitoring instruments play a vital role in predicting mountain landslide disasters. By deploying displacement monitoring stations, landslide stress monitoring stations, and groundwater monitoring wells, the dynamic changes of landslide masses can be monitored in real time. This monitoring data can help predict the probability and scale of landslides.
[0007] 3. Application of Remote Sensing Technology
[0008] Remote sensing technology, with its advantages of wide coverage and rapid information acquisition, plays a vital role in predicting mountain landslide hazards. Using satellite remote sensing and drone remote sensing techniques, high-resolution imagery of landslide areas can be obtained, extracting morphological characteristics and texture information of the landslide mass, and subsequently analyzing its development trends and potential hazards.
[0009] 4. Time Forecast and Classification
[0010] Temporal forecasting is the process of predicting when a landslide will occur. By comprehensively analyzing monitoring data and remote sensing information, we can determine the stability of the slope and predict the likely timeframe for a landslide. Furthermore, landslides can be classified based on factors such as scale, speed, and impact area, providing a basis for developing early warning measures.
[0011] V. Forecasting Methods and Models
[0012] Forecasting methods and models are at the core of landslide disaster prediction. Currently, commonly used forecasting methods include physical models, statistical models, and artificial intelligence models. Physical models are based on mechanical principles and geological conditions, statistical models use historical data for statistical analysis, and artificial intelligence models use machine learning algorithms to learn and predict from monitoring data.
[0013] 6. Precipitation Parameter Forecast
[0014] Precipitation is an important factor affecting the occurrence of mountain landslides. By monitoring and predicting rainfall, it is possible to determine whether the landslide area has the conditions for landslides to occur. Therefore, rainfall parameter forecasting is of great significance in the prediction of mountain landslides.
[0015] However, the above traditional schemes basically predict mountain landslide disasters from a single dimension, and then combine the prediction results of multiple single dimensions as the final prediction result. There are few that predict mountain landslide disasters from multiple dimensions. Summary of the Invention

[0111] If the real-time longitudinal displacement is greater than or equal to the mean, and / or the real-time lateral displacement is greater than or equal to the mean, an early warning is issued; if the real-time longitudinal displacement is less than the mean, and the real-time lateral displacement is less than the mean, no early warning is issued.
[0112] It is clear that the above-mentioned embodiments can be used in combination, such as comparing the real-time longitudinal displacement with the average of the first longitudinal displacement, the second longitudinal displacement, the third longitudinal displacement, the fourth longitudinal displacement, the fifth longitudinal displacement, the sixth longitudinal displacement, the seventh longitudinal displacement, the eighth longitudinal displacement, the ninth longitudinal displacement and the tenth longitudinal displacement, and comparing the real-time lateral displacement with the average of the first lateral displacement, the second lateral displacement, the third lateral displacement, the fourth lateral displacement, the fifth lateral displacement, the sixth lateral displacement, the seventh lateral displacement, the eighth lateral displacement, the ninth lateral displacement and the tenth lateral displacement; if the real-time longitudinal displacement is greater than or equal to the average, and / or the real-time lateral displacement is greater than or equal to the average, an early warning is issued; if the real-time longitudinal displacement is less than the average, and the real-time lateral displacement is less than the average, no early warning is issued.
[0113] It can be understood that historical data and real-time data correspond to each other. For example, if the historical rainfall during surface fitting is the average daily, weekly, monthly, and annual rainfall, then the real-time rainfall substituted into the equation is also the corresponding average daily, weekly, monthly, and annual rainfall, and so on for the rest of the data.
[0114] It can also be understood that the specific monitoring positions of the landslide body stress can be set according to actual conditions, such as around and in the middle of the slope of the landslide body. The data finally used is the landslide body stress, which is the average of the monitoring results of all positions, and the rest of the data is similar.
[0115] It can also be understood that the landslide body corresponding to the historical data and the landslide body corresponding to the real-time data can be the same landslide body, or they can be landslide bodies that are similar in one or more aspects, such as the geological structure, stratigraphic lithology, geological structure, and groundwater distribution of the landslide area; the higher the similarity, the higher the prediction accuracy.
[0116] The present invention uses surface fitting to take into account rainfall, longitudinal displacement, lateral displacement, groundwater level, rainfall intensity, rock strength, rock hardness, vegetation coverage, tree inclination, landslide body stress, longitude and latitude of the highest point of the landslide body soil, the impact of these data on the occurrence of landslides, and the degree of influence of these data on each other, that is, to predict and warn mountain landslide disasters from multiple dimensions. The prediction and warning effect is good and the accuracy is high. Even if no warning is issued, the changes in the current landslide body can be seen based on the comparison results.
[0117] The embodiments of this specification also disclose an early warning system for mountain landslide disasters, which is used to implement any of the above-mentioned early warning methods for mountain landslide disasters. The early warning system for mountain landslide disasters includes: a first acquisition module, which is used to acquire historical data of the landslide body where the mountain landslide disaster occurs, wherein the historical data includes rainfall, longitudinal displacement, lateral displacement, and groundwater level;

[0120] The second acquisition module is used to obtain real-time data of the landslide body to be predicted and warned, wherein the real-time data includes real-time rainfall, real-time longitudinal displacement, real-time lateral displacement and real-time groundwater level;
[0121] a first displacement acquisition module, configured to substitute the real-time rainfall into the rainfall surface fitting equation to obtain a target value, and if the target value is greater than 0, obtain a first lateral displacement and a first longitudinal displacement corresponding to the real-time rainfall based on the first prediction domain;
[0122] a second displacement acquisition module, configured to substitute the real-time groundwater level into the groundwater level surface fitting equation to obtain a target value, and if the target value is greater than 0, obtain a second lateral displacement and a second longitudinal displacement corresponding to the real-time groundwater level based on a second prediction domain;
[0123] A comparison and warning module is used to compare the real-time longitudinal displacement with the average of the first longitudinal displacement and the second longitudinal displacement, and to compare the real-time lateral displacement with the average of the first lateral displacement and the second lateral displacement; if the real-time longitudinal displacement is greater than or equal to the average, and / or the real-time lateral displacement is greater than or equal to the average, a warning is issued; if the real-time longitudinal displacement is less than the average, and the real-time lateral displacement is less than the average, no warning is issued.
[0124] It is understandable that corresponding functional modules may be added when implementing the methods of the above embodiments.
