| 摘 要： | 将库仑土压力假定与条分法相结合,采用与滑裂面相平行的微条对滑动楔体进行划分,并对微条进行受力分析,建立了平衡方程,推导了主、被动土压力计算公式。分析表明:土压力沿墙高线性分布,土压力大小与库仑理论的计算结果一致。

| Abstract: | A method combining Coulomb's concept with slice method was proposed to analyze the earth pressure.Sliding mass behind a retailing wall was divided by micro slice paralleling to sliding plane.Then equations were set up by considering the equilibrium of the forces on micro slice and the expression of the active and passive earth pressure was derived.It was shown by calculation that the earth pressure distribution along the wall back is linear and the results of earth pressure are agree well with Coulomb of earth pressure theory. |
