摘　　要：某水电站厂房后边坡施工过程中揭露了一非典型性的楔形体,据现场获得的裂隙面参数和楔形体几何参数,用全空间赤平投影法确定了其滑动模式,采用块体理论矢量法进行其自然条件和饱水工况下的稳定性分析。为后期的加固处理设计提供了一定的依据。An atypical wedge is exposed during construction of rear slope of the power house.Base on the parameters of fracture surface and geometry parameters of wedge obtained from field investigation,the first,sliding model of the wedge is determined by the method of stereographic projection of vector,the second,stability analysis in both natural conditions and saturated water are made by vector method,which provided some basis for the design of reinforcement in the late period.

关 键 词：块体理论 全空间赤平投影 滑动模式 矢量法 稳定性分析
