Abstract

Abstract

Bedding rock landslide exists widely in slope engineering. Its movement distance is an important parameter to characterize the landslide form and a significant index for risk evaluation. Based on the analysis of the evolution process, the runout distance of the bedding rock landslide is obtained by the theoretical derivation, and the achievements are applied to the Xinjianan landslide. The results showed three parts consisting of movement distance. The horizontal distance of the block in the air is the first, and the mobile distance of the collision with the ground is the next while the sliding distance on the ground is the last. Besides, the relative error between theoretical calculation and the actual measurements selected for the three profiles of the landslide are 9.99%, 2.53%, and 0.58% respectively. The error is small and shows the good application of the model. The research has a reference value for predicting and preventing this type of landslide.
