Numerical Analysis for Excess Pore Pressure Dissipation Process for Pressed Pile Installation

Tai Quan Zhou, Feng Yi Tan, Cheng Li

Open publisher page 2 citations

Abstract

The finite element analysis is performed on the excess pore pressure dissipation for pressed pile installation using the ABAQUS finite element software. The modified Cam-Clay model is used to model the soil behavior. The finite slide contact model is used to model the pressed pile installation process. Based on the geology stratum of soils and drainage conditions, the excess pore pressure dissipation process is analyzed using the proposed method. The initial excess pore pressure distribution along the pile depth and the pile radius direction is obtained. The excess pore pressure dissipation after 98 days is analyzed.
