The Impact Analysis of Pile and Soil Parameters on Compressive Capacity of Long Pile

Abstract

Using Finite-element Method to simulate prototype piles and then drawing the Load-settlement curves in order to calibrate the analysis software. When the simulation was consistent with the measured piles, taking it as the benchmark and then eight parameters were varied respectively so that the impacts on pile compressive capacity could be investigated. These parameters were soil's effective unit weight, lateral pressure coefficient, elasticity modulus, Poisson's ratio, cohesion, internal friction angle, pile's elasticity modulus and Poisson's ratio. Especially, soil's internal friction angle and pile's elastic modulus were deeply studied. The derived conclusions ranked the parameters by their influencing abilities. Furthermore, pile's elasticity modulus was emphasized to be paid high attention in long pile designing.
