地基板与地基相互作用的非线性力学响应分析

Nonlinear Mechanical Response Analysis of Foundation Plate-foundation Interaction Heterobinuclear Complexes with DTPA

利用有限元分析软件ANSYS,建立了地基板—地基土相互作用体系的三维有限元模型,比较真实的模拟了地基板与地基相互作用状态.在板边受集中荷载作用下,分析了地基土的材料非线性、地基板—地基土之间的状态非线性、地基板的长宽比以及厚度等因素,对地基板非线性响应的影响.最后,通过与实验数据的比较,结果表明,该模型可以比较真实地反映地基板—地基土相互作用的非线性响应状态.

Using general-purpose finite element program ANSYS,the three-dimensional finite element model of the foundation plate and the foundation soil with interaction system is built up.The interaction of the foundation plate and soil is simulated.When the concentrated load acts on the plate edge,such factors as the material nonlinear of soil,the nonlinear state of plate-soil interface,and the plate length and width and thickness,influence on the nonlinear response of the foundation plate are analyzed.By comparing ...
