摘　　要：利用ANSYS有限元软件,研究筏板基础与结构及地基土相互作用中的工作性状,通过分析基础混凝土强度、筏板厚度等因素对筏板基础的影响,对筏板基础进行了结构设计优化,为筏板基础的设计计算提供依据。Using finite element method software ANSYS in this paper, the effect of raft concrete strength and raft thickness on raft foundation have been studied. Through analysis the effect of strength of concrete and thickness of raft on raft foundation, optimum design of raft foundation is obtained. Thus, this research provides the basis for the design and calculation of raft foundation.
