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

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 the experiment data,the model can truly reflect the nonlinear response of the interaction status of the foundation plate-soil system.
