自平衡法静载试验在七浦塘大桥桩基中的应用

The application of self balance dead load test in Qiputang Bridge pile foundation

结合七浦塘大桥桥塔主墩大直径、深基础钻孔灌注桩自平衡静载试验工程实例,介绍了自平衡静载试验的基本原理、与传统桩基试验相比较的优越性以及其计算模型分析,解决了在水上对大直径、深基础桩基测试的工作难题。

Combined with self balance dead load test engineering example of Qiputang Bridge pier large diameter and deep foundation cast-in-place bored piles,the basic mechanism of self balance dead load test,the superiority compared with traditional pile foundation test and calculation model analysis were introduced,which resolved working difficult of large diameter and deep foundation pile test on water.
