基于群桩-土体共同作用的长短桩复合地基沉降特性研究

Research on the Settlement Characteristics of Composite Foundation with Long-Short Piles Based on Gr

  • 摘要: 基于群桩-土体共同作用理论,建立了受力变形较符合实际的长短桩复合地基计算模型,并利用FLAC3D对所建立的模型进行计算分析,较真实地揭示了柔性基础下的群桩-土体共同作用的机理,得到了路堤分层填筑施工中长、短桩以及桩间土的沉降特性和规律

     

    Abstract: Based on the group piles-soil interaction theory,a realistic model of composite foundation with long-short piles under the flexible basis was established.The calculations and analysis were carried out by FLAC3D in some reasonable hypothesis conditions.The calculation results revealed the mechanism of group piles-soil interaction under embankment,and the settlement characteristics of soil between short piles,long-middle piles in placement in layers construction were obtained
