桩顶竖向荷载对混凝土扩盘桩水平承载性状的影响

摘要

为了更全面地研究桩的破坏性状,本模拟对加载方式进行考究.研究竖向力与水平力间的相互作用对混凝土扩盘桩的性状影响.本文通过有限元分析对模型桩施加不同大小的竖向力,然后保持竖向荷载不变,逐级施加水平荷载直至桩顶产生较大位移,并通过对数据的比较分析,进一步研究竖向荷载的施加对混凝土扩盘桩水平承载性状的影响.%In order to study the failure behavior of the pile more comprehensively,this simulation has taken the loading method into consideration.The effect of the interaction between vertical and horizontal forces on the behaviors ofthe concrete plates-expanded pile is studied.In this paper,the vertical force of the model pile is applied by finite element analysis,and then we keep the vertical load constant,the horizontal load is applied to the top of the pile to produce a large displacement.The influence of vertical load on the load bearing behaviors of the concrete plates-expanded pile is further studied by analyzing the data.
