A Comparative Study on Seismic Response of Pile in Liquefiable Soils Considering Level and Sloping Ground

The catastrophic failure of pile foundations used for the support of bridges and other structures in liquefiable soils is still observed after every major earthquake. This paper presents the results of 3D finite difference analyses conducted to evaluate the influence of a non-liquefiable crust overlaid by a liquefiable crust and the pile is embedded into non-liquefiable soil layer below the liquefiable soil in level and sloping ground. The ground having a slope of 2° with the horizontal consists of three layers such as slightly cemented sand at the top and bottom, sand in the middle and water table at the ground level. Analysis was carried out for different cases of pile tip embedment into the liquefiable and non-liquefiable soil subjected to the 2001 Bhuj Earthquake motion. Results demonstrate that the maximum bending moment occurred at the interface of the liquefiable and non-liquefiable layers. Seismic displacement and bending moment values in the sloping ground are more compared to level ground.
