摘要
本文根据桩侧桩端间桩土相互作用的机理、以及桩顶沉降和桩身变形、桩端沉降的相互关系，提出了一种划分摩阻力、端承力和摩阻力产生的桩身变形、端承力产生的桩身变形、桩端沉降的方法。该方法具有如下的优点：能划分任一级荷载下的桩身变形和沉降值，摩阻力和端承力的大小。文中还将该方法和现有方法求解的结果以及实测结果进行了对比、分析。在对桩的Ｐ～Ｓ曲线进行分析的基础上，将Ｐ～Ｓ曲线划分为四个阶段，该四个阶段以作图法进行了论证。
The method proposed in this paper has the vantage that load and settlement distribution of different grades of loading can be determined.The proposed method and results in this paper have been analysed and compared with the used method and in-situ measuring results.Based on the analysis of the PS curve,four segments have been partitioned and proved by the mapping method proPOsed in this paper.
