Differential Method of thin Layer for Retaining Wall Active Earth Pressure and Its Distribution under Seismic Condition

Abstract

This paper studies the calculation of active earth pressure of retaining structure under the condition of earthquake. By comparing with the Rankine theory and Coulomb theory, we get a very good result. The analytical solutions of the previous works are for single homogeneous isotropic filling .but in this paper, the calculation formula and method are suitable for the calculating of active earth pressure of retaining wall which is for different multilayer nature filling. In this paper, the conclusion is the same with the conclusion of literature before, namely the point position of passive earth pressure is lower than the position of Rankine theory and Coulomb theory, which should also be noticed.
