| Abstract: | By analysis on rock characteristics, rock classification, rock discontinuity surface and hydrogeologic data in a open pit mine, this paper uses stereographic projection method and numerical analysis method to analyze influence of discontinuity surface on slope stability, slip tendency and safety factors in typical sections, then obtains slope stability result and failure mode in the open pit mine. Some operational suggestions aiming at slope conditions are provided at last. |
