摘　　要：滑劈破坏是自然界中客观存在的层状岩石边坡顺层滑坡的一种破坏模式,其特点是滑体上段为剪切下滑,下段被上段推挤后发生倒转破坏。文中采用刚体极限平衡理论首次给出了滑劈破坏的稳定分析理论公式,并对约束条件进行了讨论,最后以某矿为例,以罚函数优化方法进行了滑劈破坏的计算。The slipsplit failure of rock slope parallel to rock layers is a slipping pattern objectively existing in nature characterized by upper part shearing and slipping and lower part overturning. Theoretical formulae for analyzing stability of slipsplit failure are put forward and restrained conditions are discussed. The penalty function is used in optimizing method of searching the minimum factor of safety.
