摘要
利用有限元软件ANSYS,针对群桩横向力学响应问题,进行了三维有限元数值模拟.计算模型中,考虑了土体的材料非线性、桩-土界面状态非线性等因素,对群桩横向力学响应的影响.通过算例分析,验证了模型的正确性.在此基础上,进一步研究了群桩-土横向相互作用的非线性特性,计算结果对于桩基础的分析和设计,有较好的参考价值.
In this paper, by using finite element program ANSYS, the three-dimensional finite element numerical simulation on the lateral nonlinear response of pile group is discussed. The significant effect of the nonlinear soil behavior and the pile-soil interface separation on the response of pile group are studied in this model. Through comparing original test, the correctness of the model is validated. The nonlinear response of the pile-soil interaction is analyzed based on the model, and valuable conclusions are obtained to analyze and design the pile foundation.
