Simulation Analysis on Influence of Parameters of Pile on Load Transfer of Pile

Abstract:

An exponential curve model is modified for load transfer function,and matrix displacement method programmed by MATLAB language is used to the analysis of load transfer of pile. With different parameters of pile and soil as well as loading conditions,simulation analysis is made of the influence by changing the parameters of pile on load transfer mechanism of pile.Results show that the major load is transferred by the pile side and the rest is shared by pile tip when the length-diameter ratio is larger.When only enhancing the pile stiffness or increasing the length-diameter ratio,no remarkable improvement appears in the proportion shared by tip and bearing capacity of pile.
