摘要

Landslide is a geological phenomenon, which stimulated by certain predisposing factors, losing stabilityand sliding. It is the main type of geological disasters. Especially the largest number of rainfall-landslide, shallow landslide is the most widely distributed, we analysis the deformation of Rainfall-triggered Shallow Landslide in this article, we establish one-dimensional equation of motion of the landslide based on the functional principle, combi- ning with the Terzaghi consolidation principle, and study the dissipation of pore water pressure in the course of the campaign, revealing the dynamic evolution process from the movement to stop. Finally, we build a rainfall-triggered shallow landslide deformation prediction model. Taking the displacement of Dujiangyan taziping landslide for exam- ple,We deduce the rate of landslide movement, displacement and rainfall quantitative relationship by the use of mathmatic.
