In order to analyze the law of ultimate bearing capacity of the pile and numerical simulation studies to improve the bearing capacity factors,the finite element analysis software ABAQUS is used by combining with the investigation data of actual project,selected of pile and soil mechanics parameters is selected suitably and numerical simulation of the static load test of single pile is carried out.The simulation results show that through reasonable choice pile of soil mechanics parameters,simulation Q~S curves and filed measured values are well.This indicated that the use of ABAQUS finite element analysis software simulation to pile static load test is feasible.At the same time,it is beneficial to improve the ultimate bearing capacity of single pile through analyzing the effects of different coefficient of friction μ on bearing capacity.Therefore,mainly by the friction of the pile side from the pile top is transferred to the pile end bearing capacity limit friction pile;axial force transmission gradually decreases from top to bottom;changes of soil pile interaction but also to improve the ultimate bearing capacity of pile method.
