高回填软土地基中由于沉降而使基桩承受一定的负摩擦作用。结合工程现场试桩,采用有限元数值模拟及经验公式估算方法对桩基负摩擦问题进行研究,初步掌握了洋山地区基桩负摩擦的分布规律,可供类似工程设计参考。

In high back fill soft soil foundation,the settlement causes foundation pile to bear some negative friction load.The study on friction of pile foundation was carried out on the basis of combining in-situ test pile of the work and adopting finite element numerical simulation and empiric formula estimated method,the distribution regulation of negative friction of foundation pile in Yangshan area has been known well,it can give a reference to similar works.
