摘　　要：本文借助ANSY S有限元程序,结合片筏基础特点,对框架、片筏和地基的相互作用进行了三维有限元数值计算模拟研究,重点对土体参数变化对三者相互作用的敏感性进行了测试,同时也揭示了三者相互耦合作用的机理,研究结果表明厚筏基础和底层框架的刚度是调整地基不均匀沉降的主要因数。Three-dimensional finite element calculation about interactions between frame structure,thick raft foundation and soil mass have been carried in detail by using ANSYS program,and sensitivities of different soil mass parameter change on the coupling interaction have also been tested by using the three-dimensional finite element calculation results,and some mechanisms of the coupling interaction are disclosed in the paper at the same time.Research results show that bending moment of thick raft as well as the rigidity of first floor of frame structure make a major contribution for adjusting the settlement difference of soil mass.
