摘要
由于大直径桩的承载力高、变形小,与普通中、小直径桩存在明显差异。因此,不宜用中小直径桩计算理论来分析大直径桩。采用有限元法模拟大直径桩的荷载传递并进行分析,得到的结果与试验研究相符。
Large diameter piles（LDPs） have strong bearing capacity with less deformation, because there are distinguished differences in the mechanism of load transfer and deformation features between common small medium piles and LDPs, it is unsuitable to use the theory of common small-medium piles to analyze LDPs. The finite element method（FEM） program is also designed to simulate the load transfer of LDPs. The conclusions are in good agreement with the results obtained through theoretical analysis and experiment research.
