| 摘 要： | 基于墙后滑裂土体处于极限平衡的概念,根据墙后滑裂土体的静力矩平衡,提出了主动土压力合力作用点的确定方法,给出了主动土压力沿高度的非线性分布公式及其参数的确定方法,对比了文中方法与经典土压力理论及试验结果,表明文中方法与现有的试验结果相当一致。

| Abstract: | Based on the concept that the sliding soil mass behind the retaining wall is on the limit balance condition,in this paper,the method determining the application location of composite force of active earth pressure is presented by considering the static moment balance of sliding soil mass,the non-linear distribution formula of earth pressure along the height and the method determining the parameters in the formula are proposed,the results obtained from presented method,traditional theories and experiments are compared,and it shows that the results from presented method exactly coincide with the ones from existing experiments. |
