摘要

采用库仑土压力理论的假设：挡土墙土压力是由墙后填土在极限平衡状态下出现的滑动楔体产生，在该滑动楔体上沿竖向取水平薄层作为微分单元体，通过作用在单元体上的水平力、竖向力和力矩平衡条件，建立挡土墙上土压力强度的一阶微分方程式，给出了土侧压力系数、土压力强度、土压力合力和土压力合力作用点高度的理论公式，并分析了填土内摩擦角和墙背摩擦角对土侧压力系数、土压力强度、土压力合力、土压力合力作用点和墙底抗倾稳定性的影响。

Abstract

On the basis of coulomb’s concept that the earth pressure against the back of a retaining wall is due to the thrust exerted by a sliding wedge of soil between the back of the wall and a plane which passes through the bottom edge of the wall and has an inclination of

the differential equations of first order are set up by considering the equilibrium of the forces and the moments on an element of the wedge. The lateral coefficient of earth pressure

the unit earth pressure

the resultant force of earth pressure and the application point of the resultant force are obtained. The effects of the internal frictional angle of backfill and the frictional angle between the wall back and the backfill on the lateral coefficient of earth pressure

the unit earth pressure

the resultant force of earth pressure

the application point of the resultant force and the overturning stability of a retaining wall are investigated.
