摘要
In this paper, a theory of landslide model testing and application in Three Gorges reservoir area were introduced.Based on geo-mechanical model tests, the similarity ratio of similar material parameters, component of similar material and the boundary friction coefficient of the 2D earth landslide model test were derived and stated by theoretical and experimental methods.A model test of the Qianjiangping landslide in Three Gorges reservoir area reveal a two-step trigger mechanism of coexistence between retrogressive landslide and thrust load caused land-slide.
