| 摘 要： | 厚填土场地地基自身固结变形对桩基产生的负侧摩阻力不可忽视。依托实际工程现场监测资料，对厚填土场地的桩基负侧摩阻力的分布规律进行分析，提出了简化的负侧摩阻力沿轴向线性分布理论计算图及负侧摩阻力系数计算方法。通过与监测资料进行的对比分析，得到本工程填土场地基桩的负侧摩阻力系数为0.09～0.15，验证了所提出的计算方法的合理性，为以后类似场地地基桩基的合理设计提供参考依据和工程借鉴。

| Abstract: | For the thick fill foundation, due to its effects of consolidation on piles, deformation, the pile negative side fricition can not be ignored. Based on the monitoring data of the actual project site, the distribution law of the negative side of pile friction in thick fill site is analyzed; and a simplified theory calculated figure of negative side friction linear distribution along the axial, and the negative side friction coefficient calculation method are proposed. Through the comparison and analysis of the monitoring data, the negative side friction coefficient in thick fill foundation is obtained about 0.09-0.15, which verifies the rationality of the method proposed for the rational design of similar site pile foundations. |
