摘　　要：为了更准确地判断岩质边坡发生楔形体破坏时的稳定性,利用极限平衡原理,分析楔形体受力的平衡条件,推导得出了楔形四面体的安全系数.通过对典型边坡计算分析,得出边坡稳定系数.该方法适用性强,计算简单,结果与工程实际相符,可以在工程实践中推广应用.In order to determine the occurrence of rock slope stability with wedge failure more accurately,the wedge-shaped body equilibrium condition by the force was analyzed by limit equilibrium theory,and the safety coefficient of wedge-shaped body was derived.Through the analysis of typical slope,the coefficient of stability was obtained.This method has good adaptability,easy computing,it can be popularized to engineering.
