摘要
采用解析方法,建立了纯粘土边坡(0=j)圆弧滑裂时安全系数的解析表达式;利用函数取极值的条件,提出了通过求解一代数方程组来确定边坡的临界滑裂面和最小安全系数的方法;并计算了某些边坡的临界滑裂面和最小安全系数。
A formula to determine the safety factor when the circular failure surfaces appear in undrained cohesive soil (0=j) is presented in this paper. With minimization criteria of functions, a set of algebraic equations involving three variables are obtained. As a result, the critical slip surface and the minimum safety factor for a given slope are determined. As examples, several slopes are studied and the critical slip surfaces and the minimum safety factors of the slopes are computed.
