| 摘 要： | 采用薄层单元法研究挡土墙后回填土为砂性土情况下的主动土压力计算方法,通过假定破裂面为一直线,建立平衡方程组,并假设薄层单元上下面作用力相等,简化求解条件,推导出了主动土压力具体计算公式,为求解主动土压力分布提供了一个新方法。

| Abstract: | An approach for calculating the active earth pressure of cohesionless soil based on thin layer element method is discussed in this paper.Optimum mathematical model is established by supposing that the fracture surface is a line.And then assuming that the acting force on the upper surface of thin layer element is equal to the acting force on the undersurface,the expression for the active earth pressure calculates can be derived from the simplified model.Finally it provides a new method for solving the problem about the active earth pressure distribution. |
