In this paper, based on the principle of stereographic projection, the slope stability was analyzed by Lizheng software drawing stereographic projection. It is concluded that the III slope level and the combination of 1 dominant discontinuities has the possibility of oc- currence of wedge sliding instability, the possibility of wedge structure mainly through the re- maining districts consisting of sliding surface of slope is small. According to the structural charac- teristics of rock mass, the failure mode can be broken by arc failure. Some protection measures such as drainage, anchorage and side slope detection are put forward.
