摘要
采用库仑土压力理论中墙后填土滑动楔体极限平衡的概念，在滑动楔体上沿填土深度方向取单元片体进行分析，建立力平衡方程，调用标准的四阶龙格一库塔方法子程序求解此微分方程，得到作用于挡土墙上的土压力及其分布、用两个实验的测试数据对本文方法进行了检验。
Based on the Coulomb's idea of limiting equilibrium of the slide soil wedge behind retaining wall, the firstorder equation is set up by the equilibrium of force on the element flake sliced from the slide wagde. The earthpressure on the wal1 is obtained by solving the first order equation using the fourth -order Runge - Kuttascheme. The approach is verified through experimental data.
