摘要

基于Abaqus软件,对支板桩的工作特性进行了研究。为解决这一问题,考虑桩土非线性接触、土的弹塑性、初始应力状态。结果表明:桩身轴力在支板上、下两处发生突变,当支板桩承载力达到极限时,支板下坡承受较大接触压力,支板上坡与土体产生分离,支板底部与桩身发生塑性应变;

Study of working properties of pile with branch plates based on Abaqus
Based on the Abaqus software, the working properties of pile with branch plates were studied. To solve this problem and considering the no-linear contact between pile and soil, elastic-plastic of soil, initial stress state. The results show that the axial force of pile body had mutations at upper and lower of the branch plates, when the pile with branch plates bearing capacity to the limit, the lower slope of branch plate bore great contact pressure, the upper slope of branch plate and soil produced a separate, the plastic strain occurred in the bottom of the branch plate and the pile body.
