摘要
基于土—结构动力相互作用现场模型试验 ,以桩基剪切型结构为例 ,运用通用有限元软件MARC建立三维有限元模型、进行非线性地震反应分析。分析结果表明 ,桩土参与作用对上部结构地震反应有较大影响 ,上部结构相对于地基刚度越大 ,共同作用效果越明显。
Based on pile-raft foundation structure of large-scale test,a three dimensional finite model of soil-structure interaction system is established using general-purpose finite element program MARC. Seismic nonlinear analysis of the interaction system are studied. The results show that it should not be neglected for the influence of seismic response on superstructure due to the dynamic interaction of the pile-soil structure.
