Abstract
Piles supporting bridge abutments resting on soft clay are subjected to a horizontal load due to the lateral movement of the soil induced by an adjacent embankment. These lateral loads result in additional pile movement and induce additional bending moment. An accurate representation of loading, pile–soil relative movement and boundary conditions is needed for analysis of these piles. Simulating this problem using three-dimensional finite element model is examined herein. The effect of using different approaches in modelling piles and using different secondary compression index values for soft clay layer on the results of the numerical model has been investigated. Verification of the numerical model is performed by back analyzing a published case study. A good agreement between the results of the numerical model and the case study is obtained suggesting that the current numerical model can be used for investigating the short- and long-term impact of soil lateral movement on piles’ performance.
