摘要

根据库仑主动土压力系数与填土内摩擦角、坡角、墙背倾角等参数的内在关系，对库仑主动土压力系数随不同参数的变化规律进行了分析，并在原数解法的基础上推导出一种新的简易计算公式。通过数解法与简易法的对比分析表明，当保证率为95 % 时，简易法相对于库仑计算值的最大误差小于14 %。

Abstract

Based on the relations between coefficient of coulomb’s active earth pressure and internal friction angle

grading angle

slope angle

the rules between coefficient of coulomb’s active earth pressure and different parameters were analyzed. On the basis of algebraic method

a simplified solution of coefficient of Coulumb’s active earth pressure was deduced. Then the coulomb’s method and the simplified method were compared . The results show that for Coulomb solution

the maximum error of the simplified solution is less than 14 percent on the condition of 95 percent probability.
