Abstract:

The lateral earth pressure of retaining wall mainly depends on the displacement of the wall. The calculation method of earth pressure coefficient under any lateral displacement is obtained based on the asymptotic state formula of sand, which describes the different stress-strain relationships of soil under different constraint conditions of deformation, considering the relationship between principal stresses in the plane strain state and the dilatancy behavior of sand. The parameters in the formulations can be determined through simple tests. Compared with model test results, the reasonableness of the proposed method is verified.

Key words: lateral earth pressure coefficient, lateral displacement, strain increment ratio, asymptotic state, retaining wall
