Modelling the Response of Single Passive Piles Subjected to Lateral Soil Movement using PLAXIS

Abstract

Abstract-Response of single pile subjected to lateral displacements of soil mass using 3D finite element software (PLAXIS) is studied. Embedded pile feature in which the pile composed of beam elements with special interface elements to represent pile-soil interaction is used. The Mohr-Coulomb elastic-plastic constitutive model was employed for the soil stress-strain behaviour. A good agreement between laboratory and predicted results is observed in the validation analysis. A parametric study was conducted to investigate the influence of soil Young's modulus and soil movement profile on the response of single "passive pile". The software results revealed that the distribution of bending moment along the pile length vary considerably and was in a very good agreement with the real pile behaviour when adopting a variation of soil elastic modulus with depth instead of choosing a constant value.

Investigation of Pile Behavior Toward Abutment Construction using PLAXIS 3D: Case Study on Lembak Bridge

“…There are a lot of geotechnical problems caused by lateral soil movement. Soil movement itself cause by various factors such as consolidation, expansive soil, excavation, slope stability issue, embankment, and pile installation with too narrow spacing [1]. Bearing capacity, the foundation must be designed properly to ensure the building avoids problems differential settlement [2] [3].…”
