摘要

实践证明，作用于挡土墙的主动土压力沿墙高不是直线形分布，而是非线性的。采用统一强度理论，通过对滑动土体中水平薄层单元的分析，给出了墙体绕基础转动情况下土压力合力、强度及土压力分布的理论计算公式。公式推导过程中考虑了中间主应力效应的影响。结果表明，强度理论效应对土压力有很大的影响，应用统一强度理论解可以更好地发挥填土材料的强度潜力，并能获得明显的经济效益。

Abstract

It is known that the distribution of the active earth pressure against a rigid retaining wall is not linear but nonlinear. Based on the unified strength theory

the formulations of the unit earth pressures

the resultant earth pressure and its acting point are given for the wall rotating about the base by analyzing the slice elements extracted from the sliding soil wedge. The formula takes account of the effect of intermediate principal stress. It is demonstrated that the strength theory has great influence on the earth pressure; and the potential strength of the filling materials is sufficiently developed under the guidance of the unified strength theory.
