| 摘 要： | 越南某开发区大瓮桥、芹玉桥4根试桩均为钻孔灌注桩（其中两根试桩采用了桩端后压浆技术），用自平衡法进行了静载试验。简要介绍了测试方法的基本原理和桩端后压浆技术，并对试验数据进行了分析。试验结果表明，越南规范高估了桩端承载力，桩端后压浆可以大幅度提高承载力。

| Abstract: | Four test bored piles in Daweng bridge &; Qinyu bridge projects in Vietnam have been tested with self-balanced method of bearing capacity. The pile tip post-grouting technology was used in two of them. The fundamental principles of this method and the pile tip post-grouting technology are introduced. The experimental data gained are analyzed. The results indicate that the design codes of Vietnam over estimate the tip bearing capacity; and the pile tip post-grouting can boost the bearing capacity of piles. |
