【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作用下安全稳定的关键。在分析桩-土间相互作用的基础上,利用有限元分析软件ANSYS中的Structural模块先进的非线性功能,进行桩的有限元分析,对桩-土间相互作用方式进行了数值模拟研究。建立了完整的桩模型,并建立弹簧单元以及表面效应单元以模拟土层对桩的作用力,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,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,the structural module of the finite element analysis software ANSYS was used to analyze the pile under the construction loading,and an integrate pile model was built along with the elastic element and surface effect element,which simulated the pile-soil interaction.Finally,it was got the pile displacements and its stress distribution through Y direction under construction loading,which provided theory evidence for the construction foundation design.更多还原
