Abstract
The time dependent response of the pile foundation can be categorized as one of the effective parameters that should be taken into account during analysis and design stage. From the literatures, very few reports are available on lateral response of the pile especially on the effect of soil type. It seems to be no exact solution for laterally loaded pile foundations in consolidating elasto-plastic soil to determine the design parameter such as maximum lateral pile displacement, ultimate lateral soil resistance and p-y relationship. Therefore, this study investigates the effect of soil type with different intensities of loading on the lateral pile deformation and lateral soil pressure with time. Finite element analysis is carried out to evaluate the lateral pile response embedded in cohesionless and cohesive soil subjected to pure lateral load. The simulation include linear elastic model to represent the pile structural material and Mohr-Coulomb elasto-plastic model to represent the surrounding soil. Biot’s equation of consolidation is used to govern the elasto-plastic material. The complete model of the whole geotechnical system are used to assess the lateral pile displacement and lateral soil pressure developed at pile face of 15m pile length and 1m pile diameter. It is shown that the lateral pile displacements increased and the lateral soil pressure was redistributed with time due to consolidation process.
