Simulation of Load Bearing Capacity of a Single Pile in a Multi-layered Soil

Abstract

AbstractThis paper deals with the modelling of load-deformation behaviour of a circular footing on sandy stratum in a two-layered soil system. The main goal of this study is to evaluate the settlement and bearing capacity of a circular pile supported by a sandy soil multilayer constructed on a soft clay foundation. This article discusses the main principles of pile capacity calculations with the help of Abaqus software. Two traditional methods are used for determining pile load capacity: (1) the α method and (2) β method. The alpha technique determines the short-term load capacity of piles in cohesive soils. In contrast, the beta method determines the long-term load capacity of piles in both cohesive and cohesionless soils. A model generated using finite element software is utilised for numerical analysis. The findings for load settlement diagrams and bearing capacity obtained from numerical results are similar with those obtained from finite element analysis.KeywordsBearing capacityCircular footingNumerical analysisα method and β methodFinite element method
