STUDY ON PHYSICAL MODEL TEST OF QIANJIANGPENG LANDSLIDE
Model test is one of important tool to study mechanism of landslide. 17 commonly parameters of landslide model test were derived based on similar theories of landslide physical model testing in the paper. The large-scale rainfall landslide physical model test platform was used. Aiming at aberration of traditional similarity theory in landslide geo-mechanical model test application, correction method of aberration was brought forward. The new similar conditions and similar environment of landslide test physical model was built. Model test of Qianjiangping landslide in Three Gorges reservoir area has revealed the two-step trigger mechanism of coexisting with retrogressive landslide and thrust load caused landslide, and through model aberration correction method, landslide the ultimate displacement of profile were predicted that its results has good consistency with the calculated results by DDA.
