Abstract
Combining the explicit Lagrangian difference method for the continuum body and strength reduction technology, this paper analyzed the stability of Xian Feng open-pit. The generalized shear strain and plastic strain interconnected within the weak structural plane of slope are used as criterion to identify slope failure state. Analysis of the example verifies that the criterion is rational. With the calculate model, it can predict the open-pit ultra-high slope stability after five years. Its results are similar to the traditional limit equilibrium method. Therefore, the method is reasonably practicable. So the result will be important significance to guide the post-construction of mine.
