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.
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.
