The invention discloses a landslide prediction method based on elastic waves, which is applied to the technical field of landslide prediction, and specifically comprises the following steps: constructing a multi-target landslide probability prediction model; acquiring an elastic wave signal propagated in the slope; picking up signal features of the elastic wave signal by using a feature extraction network; and substituting the signal features into an equation of the multi-target landslide probability prediction model, and judging whether the landslide occurs or not. According to the landslide prediction system and method based on the elastic waves, a multi-target landslide prediction model is constructed, the prediction result is determined by utilizing the wave velocities of the elastic waves at different moments, the prediction precision is greatly improved; the elastic wave propagation process is segmented into different time periods by utilizing the segmentation principle, the wave velocities are calculated respectively for judging whether a landslide occurs or not, further substituting historical data into the multi-target landslide probability prediction model, determining an elastic wave velocity threshold value of the landslide, and determining whether the landslide occurs or not according to different wave velocity durations and the current wave velocity.
Description
technical field [0001] The present invention relates to the technical field of landslide prediction, in particular to a landslide prediction method and system based on elastic waves. Background technique [0002] At present, landslides, as one of the major geological disasters, cause a large number of casualties and property losses worldwide every year. Applying the most advanced landslide monitoring and forecasting system to monitor slopes on a regional scale is of great significance for predicting the occurrence of rainfall-type landslides. Therefore, there is an urgent need to monitor slopes with potential landslide hazards, provide early warning for potential disaster victims, and provide reference for analysis and disaster relief. [0003] To date, various slope monitoring techniques have been widely used as early warning systems. Furthermore, the elastic wave properties contain a lot of information related to the stress state of the soil. Non-destructive analysis of...
