摘要/Abstract

摘要： 从分析微楔体静力平衡的方法入手,导出了墙背仰斜时的被动土压力计算公式,它既可直接适用于砂性土,又可直接适用于粘性土,克服了使用库伦公式计算粘性土土压力时需利用等代内摩阻角的不足.本文公式可适用于更一般的情况.

Abstract: According to the analysis of the static equilibrium of finite sliding wedge, the formular of the passive earth pressure about the inclined retaining wall has been given.It can be used not noly for sand but also for clayed soil.It compensates the shortage of the Rankine's earth pressure theory and the Coulomb's earth pressure theory which are both directly used for sand.The formula in this paper can be used for more common cases.

Key words: clayed soil, finite sliding wedge, angle of limit rupture
