Abstract
In the landslide stability calculation and engineering design, it is very important to get the fight value of cohesion (C) and internal friction angle (φ) for the sliding zone soil. Firstly, this paper uses the finite element analysis method to conduct stress simulation analysis of the landslide slope. Then, by adopting related physical index and intensity properties of laboratory testing indicators of sliding zone, it can invert the strength parameters of the slipping surface, and the inversion results are very close to the value of indoor direct shear test of the sliding zone soil strength parameters. It provides a reasonable basis for the calculation of landslide stability in the selection of parameters, it also proposed a well-established,and more careful method for the inversion strength parameters of sliding surface.关键词
