Numerical Analysis for Retaining Walls Subjected to Swelling Pressure

Abstract

A simplistic model of lateral swelling force is coupled with the standard elastic Euler Beam equation to form a nonlinear two point boundary value problem for modeling of soil or rock retaining wall deflection. Numerical simulations are performed using experimental data for the parameters in the model with fixed-free end boundary conditions on some typical retaining walls. Deflections and bending moments for the walls with uniform cross-sections and walls with tapered cross-sections are obtained numerically. Several approximation schemes are implemented by using MATLAB scripts and a quite different scheme is implemented by using ANSYS with APDL scripts. It is demonstrated that the numerical solutions obtained by the two different numerical procedures converge to a common solution in several cases with engineering data for some expansive clay under certain moisture conditions. This is an initial attempt to calculate deformations and bending moment of more realistic soil retaining structures subjected to expansive soil swelling force by a mathematical model and numerical simulation.
