本文通过现场试桩资料， 分析了桩的荷载传递机理与承载性状， 对于大直径桩， 其变形特征为缓变型，不具有明显的破坏特征点， 其极限承载力或容许承载力的确定以位移控制，沉渣厚度对桩端阻力及桩侧摩阻力的发挥有重要影响。
In this paper, the load transfer mechanism and load-bearing characteristics of piles are analyzed through on-site pile test data. For large diameter piles, the deformation characteristics of the pile are slowly changing without obvious failure characteristic points. The ultimate bearing capacity or allowable bearing capacity is determined by displacement Control, sediment thickness of the pile tip resistance and pile lateral friction has an important impact.
