Landslide slip distance prediction method

Abstract

The invention discloses a landslide slip distance prediction method which is used for predicting the size of a landslide slip distance with a landslide risk, and the method is realized by adopting thefollowing steps: step ST100, setting landslide body parameters; step ST200, determining a parting surface of a landslide body; step ST300, establishing a slip distance prediction model composed of astarting section, an acceleration section and a deceleration section; and step ST400, fitting the landslide body into a mass, and step ST500, after fitting the landslide body into the mass, calculating the slip distance of the landslide body by taking the center of the mass as an object. According to the slip distance prediction method provided by the invention, the original topographic map is used as a basis for data parameters required in the model, and the actual measurement and calculation content is revised in combination with kinetic energy loss possibly generated by differential motion,landslide mass disintegration and the like in the landslide mass motion process, so that the final calculation result is small in distortion degree and high in fitting degree and goodness of fit withactual data; and the slip distance of the landslide body can be reflected more accurately.

Description

technical field [0001] The present invention relates to the field of geological disaster prediction methods, in particular to areas where landslides are prone to occur, a method for predicting the slip distance of possible landslides after scientific measurement of possible landslides and mountain bodies after on-site inspection, and in particular to a landslide Slip prediction method. Background technique [0002] Landslides are an extremely complex geological and geomorphic system, and their 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 range prediction models at home and abroad mainly include three types. One is to regard the sliding body as a mass p...
