A Comparison of Numerical Algorithms in the Analysis of Pile Reinforced Slopes

The paper describes the influence of pile reinforcement on the stability of slopes through numerical analysis. Included in the paper is some discussion of the modifications made to include pile reinforcement in an existing finite element slope stability program that uses the strength reduction method. Then the finite element program developed is compared for accuracy in the solution of the piled slope problem with a popular proprietary code that uses the finite difference method. Finally, parametric studies are presented to assess the influence of pile location and length on the slope stability.
