荷载箱安装技术要点及改进方法——基于自平衡法静载试验

Technical points and improvement method in load cell installation——Based on the static loading test of self-balanced method

福建省的单桩竖向抗压静载试验荷载越来越大,引起诸多问题,自平衡法静载试验可解决传统静载试验的困境。文章介绍了自平衡法静载试验原理,并结合桩基检测实践,系统总结了荷载箱安装技术要点、常见问题、可能导致的问题及规避解决的措施,最后提出了一种改进荷载箱安装的方法。

Ultimate load of static loading test of the single pile in Fujian province is increasing, and it brings many problems. The static load test of self - balancing method can solve the actual difficulty of traditional static loading test. The paper introduces the principle of the static load test of self - balancing method. Based on practical pile foundation detection, the paper summarized technical points in load cell installation,consequences of common problems and solutions. Finally a kind of improved method for load cell installation is put forward.
