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。
The Coulomb earth pressure assumption and the strip division method are combined. The sliding wedge body is divided by the micro strip parallel to the sliding surface, and the force analysis of the micro strip is carried out. The equilibrium equation is established and the formulas of the primary and passive earth pressure are deduced . The analysis shows that the earth pressure is highly linear distributed along the wall and the earth pressure is consistent with the calculated result of Coulomb theory.
