Post-wall Earth Pressure Analysis of Rigid Retaining Wall Based on ABAQUS in T Displacement Mode

Abstract

In this paper, the finite element numerical model of rigid retaining wall structure is established by using ABAQUS finite element calculation software. The retaining wall structure of the same section is used to reach the limit of gravity retaining wall by displacement in T displacement mode Equilibrium state, calculated in the retaining wall behind the filling capacity of the γ, the friction angle φ, cohesion C and fill the surface of the uniform load q and other conditions under the retaining wall of the static earth pressure, active earth pressure and the distribution of passive earth pressure, and compared with the classical Rankine's earth pressure, and obtained the ABAQUS finite element software to simulate the active earth pressure soil of the retaining wall under different working conditions, The distribution of pressure and the variation law can be simulated well, so it is feasible to use ABAQUS finite element software to solve the geotechnical problem.
