摘要
基于ABAQUS大型有限元分析软件,建立了桩基厚承台非线性有限元分析的计算模型,并对文献中二桩厚承台进行了分析,计算值与试验值吻合较好,表明所建立的有限元计算模型可较好地模拟二桩厚承台的性能。运用所建立的模型,分析了二桩厚承台内部完整的力流分布,探讨了其受力机理,为桩基厚承台传力模型的建立提供了理论依据。在理论分析和以往研究的基础上,提出了二桩厚承台的桁架模型,可供二桩厚承台设计时参考。
The non-linear finite element analysis（NFEA） model of thick pile cap was established by using ABAQUS software.Two-pile thick caps in literature were analyzed by using the NFEA model proposed in this paper.Analysis showed that the theoretical values were in good agreement with experimental values,and that the behavior of two-pile thick caps could be simulated by using the NFEA model.Besides,the internal integrated force flow distribution of two-pile thick caps was analyzed,and their stress mechanism was researched,which can provide theoretical calculation basis for establishing load transfer model of two-pile thick caps.On the basis of theoretical analysis and the previous studies,the truss model of two-pile thick cap was put forward.
