| 摘 要： | 在分析桩侧极限摩阻力与桩长规律的基础上，通过桩侧摩阻力在桩尖平面应力分布的合理假设，推导了桩尖附近应力场公式，得出了桩尖附近最大地基应力与桩长、桩径、桩周土内摩擦角和桩顶荷载的规律以及影响桩尖应力的敏感因素，为桩尖附近其他地下结构的验算提供依据。

| Abstract: | Based on analyzing the regularity of relation between side ultimate friction resistance and pile length, under reasonable assumptions of stress fields near pile tip caused by side friction resistance, formulae for foundation stress fields near pile tip have been derived. The relations between the maximum stress and some sensitive factors such as pile length, pile diameter, internal friction angle of soil and load of pile top are deduced. The study provides useful references to the analysis of other underground structures near pile tip. |

| Keywords: | vicinity pile tip side friction resistance distribution maximum stress near pile tip |
