Abstract

With the continuous development of numerical simulation technology, It shows the great advantage for FLAC software in geotechnical simulation. This paper FLAC combination with the strength reduction technology, and applied to slope stability analysis, to calculate the stability of the slope coefficient and the approximate location of the potential slip surface and shape, It provides the basis for engineering practice. By the law, the evaluation of slope stability analysis for North Opencast coal mine of YiMei, it determine the stability of the slope coefficient and the location of dangerous side, it was validated by the rigid body limit equilibrium method, the results of the analysis method is feasible.
