一种改进的桩身竖向应力测试方法

An improved test method of pile vertical stress

本文根据单桩竖向抗压静载试验中,桩侧摩阻力的计算原理,对《建筑基桩检测技术规范》(JGJ106-2003)推荐的桩身竖向应力测试方法作了改进,然后从理论上对该方法的桩侧摩阻力分析方法和试验数据的整理过程进行了探讨,并结合工程实例论证了该方法的可行性和简便性。

Based on the calculation principle of pile side friction resistance in the static loading test of single pile, the recommended method of pile vertical stress test of the＂building foundation pile test specifications （JGJ106-2003）＂has been improved, and then theoretically the analysis method of pile side friction resistance and experimental data colla- tion process was discussed. The feasibility and simplicity was demonstrated with an engineering example. The method can be referenced for the majority of engineering practitioners.
