Parametric Study of Lateral Displacement Due to Pile Group Installation

Abstract

Pile installation generates lateral ground movement and excess pore pressure surrounding it. Both are causing problem to the existing adjacent earth structures. The objective of this paper is to do sensitive analysis of lateral ground movement due to pile group installation. Pile numbers, diameter, and spacing are the parameters to be considered. Plaxis is utilized to do numerical analysis and pile installation is modeled using displacement controlled cavity expansion. The lateral displacement – pile group correlation charts are proposed based on the simulation results. The charts are useful to predict the lateral displacement on pile group design
