| 摘 要： | 提出计算竖直受力桩的位移协调法，具有模型简单、参数易取的优点。用来分析桩侧土影响半径rm，结果表明，随着桩顶荷载P增大，桩长细比L/d增大，都会使rm扩大；土质越好，rm越小。此外，也说明，现行建筑基础规范中有关桩间距规定的合理性。

| Abstract: | The displacement-coordinating method has been put forward to analyze the influencing radius rm of pile. The method has the advantages of simple model of soil and parameters obtained easily. The results show that larger influencing radius can be brought about with the larger load on pile top or larger slenderness ratio of pile; and better soil can have smaller influencing radius. In addition, the concerned provisions about the spacing between two piles listed in current code for design of building foundation have been proved rational. |
