摘　　要：利用全空间赤平投影和矢量计算对边坡关键块体滑动方向、结构面交点、面积、体积和安全性建立了计算方程。同时结合可靠度理论给出关键块体失效概率评价式。最后以五面结构岩体为例说明所建方程的应用。The calculation equations for sliding direction, plane intersection points, area, volume, and safety of key blocks of slope are established by stereographic projection of vector and vector calculation. The equations of failure probability are also given based on the reliability theory. As an example, the equations are used in the stability analysis and reliability evaluation of the five-plane construction rock mass.
