本文根据库仑的概念，即挡土墙墙背上的土压力是由墙背与通过墙底边缘的倾斜度为θ的平面之间的滑动楔土所产生的推力引起的，并考虑楔土单元上的力和力矩的平衡，建立了一阶微分方程。得到了土压力侧向系数、单位土压力、土压力合力和合力作用点。研究了填土内摩擦角和墙背与填土间摩擦角对挡土墙侧压力系数、单位土压力、土压力合力、合力作用点和抗倾覆稳定性的影响。
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 ofθ , 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.
