挡墙土压力理论新探

FURTHER RESEARCH ON EARTH PRESSURE OF RETAINING WALLS

传统土压力理论的主要弊端在于它们均建立在极限平衡理论基础之上;认为土压力的产生与土体的实际应力分布状态无关,尽管认为土压力与土体位移有关,但又不作位移分析。为此笔者提出一种以应力分析为基础的土压力理论,以消除传统土压力理论的上述缺陷。

The traditional theories of earth pressure for retaining walls are based on the limit equilibrium. They incorrectly assume that the earth pressure is independent of the stress state in the soil around the wall. Although they point out that the earth pressure is closely related to the soil deformation, nothing about the computation of it has been done. In this paper a new method for the calculation of the earth pressure based on the stress analyzed by FEM is proposed, The weakness of the traditional theories can be overcome in the new method.
