摘　　要：为了准确判断岩质边坡的稳定性,有效指导边坡的设计与施工.利用极限平衡原理,引入岩质边坡裂隙水压力,推导了边坡稳定性的安全系数公式.通过对典型边坡采用圆弧条分法计算分析,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,对设计和施工有借鉴意义.In order to decide the stability of rock slope accurately and instruct the design and construction effectively,slope circular sfice method was expounded. With the limit equilibrium theory and fissure water pressure on the back edge, the safety coefficient equation of slope was deduced. The typical slope was calculated with circu- lar slice method, the coefficient of slope stability was got. This method has good adaptability, easy computing and accurate result, it has special reference to design and construction.
