5. Abstract : based on soil plasticity and limit analysis theory , the second failure surface of backfill behind retaining wall with gentle back surface are studied from two view points of maximum active soil pressure and minimum resistive overturning safety factor , and it is further considered that the minimum resistive overturning safety factor is the best approach to studying the failure mechanism of backfill under complex back surface conditions of retaining structures
   文摘:基于土的塑性极限分析理论，从挡土墙最小抗倾覆安全系数和挡土墙背上的最大主动土压力两个角度，分别研究了坦墙后土体中第二破裂面的位置，认为在复杂的挡土结构墙背条件下，用最小抗倾覆安全系数来研究挡土墙后土体的破坏机制较为合理。
