| 摘 要： | 本文采用有限单元法分析弹性地基上的片筏基础,可分别模拟片筏基础和地基土,考虑土的层状分布,将地基模拟成分层地基,并考虑土与基础的共同作用,使计算模型更符合实际。通过典型实例,比较了Winkler地基,弹性半空间地基和分层地基对计算结果的影响,并探讨了片筏不同刚度和不同地基条件对计算结果的影响,得到了一些有实用意义的结论。所编EFP程序可在IBM—PC上运用。

| Abstract: | In this paper,the raft based on elastic foundation is analysed using Finite Element Method.The raft and soil medium are modeled respectively.In the analysis,the multilayer model of the soil medium and the interaction between the raft and soil are used.A typical piste is analysed.For comparison,the different soil models,i.e.winkler,multilayer and halfspace,the different stiffnesses of raft and different subground conditions are considered.Some very interesting results for design are obtained.The method herein is very useful for raft design which can not use the simplified method stipulated in the new foundation specification.The program EFP is coded in F77.It can be run on the small computer IBM-PC. |
