| 摘 要： | 扩径桩能够充分发挥土层和桩身的承载潜力，使承载力大幅度提高，同时减少沉降，但由于其桩身在某深度发生扩径突变，给研究扩径桩的荷载传递性状带来不便。现有对扩径桩的研究只限于小直径桩的模型试验以及有限元分析，文章在扩径桩现场竖向静载荷试验的基础上，对扩径桩承载力、荷载传递特性进行了分析，为该类桩的研究提供参考。

| Abstract: | The Pile with expanded diameter is a new kind of pile which has the advantages of high bearing capacity and little subsidence.Because of the difference of the diameter, research on the load transfer mechanism is difficult.The research on the pile with expanded diameter is limited to the pile model test and Finite Element Analysis.On the basis of results of the static loading test on pile with expanded and the researches on bearing capacity and the load transfer mechanism, this paper predicts new points,it will be a theoretic reference to use this new type of pile in engineering. |
