A method for predicting landslide distance

Abstract

This application discloses a method for predicting landslide distance, which is used to predict the size of the landslide distance in a landslide risk, which is realized by the following steps: Step ST100 sets the parameters of the landslide body; step ST200 determines the dividing plane of the landslide body, and step ST300 Establish a slip distance prediction model consisting of a start-up section, an acceleration section and a deceleration section; Step ST400 fits the landslide body to a plastid, and step ST500 fits the landslide body to a plastid, and calculates the mass center as the object. slip distance. The slip distance prediction method provided by the present invention takes the original topographic map as the basis for the required data parameters in the model, and revises the actual measurement and calculation content in combination with the kinetic energy loss that may be caused by differential movement, landslide body disintegration, etc. during the movement of the landslide body. The distortion of the final calculation result is small, and the degree of fit and agreement with the actual data is high, which can more accurately reflect the slip distance of the landslide.

Description

technical field [0001] The invention relates to the field of geological disaster prediction methods, in particular to a landslide-prone area, a method for scientifically measuring a possible landslide mountain after on-site inspection, and obtaining a value for predicting the slip distance of a possible landslide, in particular to a landslide Slippage prediction method. Background technique [0002] Landslide is an extremely complex geological and geomorphological system, and its development characteristics are affected by the occurrence area, topographic and geological conditions, internal and external dynamic conditions, climatic conditions and human engineering activities, and have great uncertainty. Therefore, it is unrealistic to try to establish a universally applicable landslide spatial prediction formula. At present, the more mainstream ranging prediction models at home and abroad mainly include three types. One is that the sliding body is regarded as a particle, an...
