【摘要】 桩-土间相互作用机理的研究是保证桩基础在建筑荷载下安全稳定的关键。本文在分析建筑荷载下桩-土间相互作用机理的基础上,利用有限元分析软件对桩在建筑荷载作用下桩-土之间相互作用方式进行了有限元数值模拟研究,采用弹簧单元以及表面效应单元模拟土层对桩的作用力,建立了完整的桩-土作用模型,并得到了在建筑荷载和土层作用力下桩的位移量及其轴向应力分布。该研究可为建筑基础设计提供理论依据。更多还原

【Abstract】 Research on the action mechanism between pile and soil is the assurance to the stabilization of pile under construction loading.Based on the analysis of interaction between pile and soil under construction loading and by using the structural module of finite element analysis software Ansys,this paper analyzes the pile under the construction loading,builds an integrate pile model along with the elastic element and surface effect element,and simulates the pile-soil interaction.The pile displacement and its stress distribution through Y direction under construction loading are obtained and provide theoretical evidence for the construction foundation design.更多还原
