摘要
基于某大型有限元软件建立了三维桩土分析有限元模型,分析了负摩阻力的形成过程,揭示了摩擦型、端承型桩负摩阻力工作性状的异同,研究了桩顶荷载大小对桩侧负摩阻力的影响,得出了一些有益的结论。
Based on a large-scale finite element analysis software,it is established about the three-dimensional finite element model of pile and soil,and analyzed the forming process of negative friction,reveals the similarities and differences of friction,end bearing pile negative skin friction behavior,the influence of pile top load on pile side friction resistance,draws some useful conclusions.
