摘要
以软粘土基坑为例 ,采用解析方法建立了基坑圆弧滑裂时其安全系数的解析表达式 ;利用函数取极值的条件 ,推导出了确定基坑临界滑裂面的迭代算式 ,获得了基坑的临界滑裂面。
Using analytical method, the calculated formula of the safety factor is established in the case of a circular failure surface for foundation dig. Using the conditions that a function takes on the minimum value, two alternating algebraic equations are given to determine the most critical slip surface for foundation dig,and the most critical depth of slip surfaces and the minimum safety factors are obtained
