根据瞬态分析计算了不同时刻边坡的应力值，利用局部破坏判别法，确定了对应初始点的滑动路径，取瑞典条分法计算公式作为目标函数，运用鱼群算法得到了初始点，进而确定了滑动路径，最后，通过对各个时刻的边坡安全系数数据的分析，得到了边坡滑坡的失效概率及可靠度，并结合实例说明了此种方法的有效性。

Based on transient analysis,stress value and values of principal stress of slope can be got at each time. Then based on partial failure discriminance,the only slip plane can be got to some initial point. Based on sweden slice method,formula of the safety coefficient of the slope’s stability can be as objective function,through artificial fish-swarm algorithm,slip plane can be established. Finally,through analyzing the safety coefficient of the slope’s stability and initial point in each time,the structure reliability of slope stability and failure probability can be got. This method is verified by an example,which proved that the method is feasible and available.
