Theoretical Study On The Settlement Calculation Of Pile Foundation And ANSYS Numerical Simulation Analysis

At present the essential method for the pile foundation settlement calculation are the ground standard and the pile foundation standard in the engineering field, but the base theory of standard computational method is the settlement theory of shallow layer foundation, we can say, the shortcoming of shallow layer foundation settlement computation has taken to the pile foundation settlement computation similarly, from some literature and this article's analysis we can find, at present the pile foundation settlement calculation mainly existence as follows lacks limits: 1) the elementary settlement calculation theory of shallow layer foundation is the isotropic homogenous theory of elasticity, this theory has neglected the influence of foundation rigidity; 2) the determination of the ground calculation depth is unreasonable; 3) the modulus of compressibility of stratified soil has some problem; 4) the existing literature is unreasonable to the application of Geddes' solution and unable to solve the settlement calculation problem of the single pile when the skin friction is on non-linear distribution.This article mainly aims at the above question, analyzes and discuss the settlement calculation of the pile foundation by using the theory of elasticity and the traditional layerwise summation method, and carries on the numerical analysis and the value simulation analysis with the aid of the important mathematics software Matlab and the finite element computation software ANSYS, then obtains many conclusion which is beneficial in the actual project.Main work and result as follows:1) Through comparison between layerwise summation method and classical elasticity displacement solution, analyze the difference of calculating foundation settlement between the method of Code for Design of Building Foundation and the theory of elasticity ,so does between calculated and observed settlement Expounds the effect of foundation width embedded depth of foundation and Poisson's ratio of soil on foundation settlement, and proves that the Xu Zhi-ying's solution for calculating foundation settlement based on Mindlin's equation is more perfect than the integral solution based on Boussinesq's equation.
