【Abstract】 An approximate method to compute the horizontal displacement of cement-soil retaining wall is presented,by analyzing the interaction between soil mass and the wall.The wall can be regarded as a rigid body if the ratio of its width to height is very small.The stiffness of soil spring is determined by “ m ” method,and the effect of shearing and overturning resistance of the wall weight and the soil below the wall is taken into account at the same time in this paper.By this method,the relation between the horizontal displacement and pit depth is discussed,and the yield scope of soil and the real soil pressure are simultaneously obtained. Accordingly,its stability can be judged.更多还原
