ANALYSIS OF LATERALLY LOADED PILES IN SLOPING GROUND

Abstract

The analysis of laterally loaded pile and group of pile embedded at sloping ground draw considerable attention over past several decades. In this present study, a finite element numerical analysis has been carried out on single pile and group of pile embedded at centre of sloping ground by using finite element software PLAXIS 3D. Because, the full scale experimental investigations are not so easy to conduct due to have several limitations like higher cost, uncertainties and technical difficulties. The pile foundation in sloping ground subjected to lateral loading which are more predominant to vertical loading. A detailed parametric study has been performed in PLAXIS 3D to find out the effect of sloping ground on the bending moment and lateral shear force carrying capacity along length of pile. The different parameter considered for the analysis are undrained shear strength of clay soil, L/D ratio of pile, slope angle and spacing between group of pile. Various combinations have been made by varying all geometrical and soil parameters. Finite element analysis has been carried out for each combination and results are compared by plotting graph for each combination and conclusions are drawn on the basis of results.
