自平衡法桩基静载试验在水下大桩径施工中的应用

Application of Static Load Test of Pile Foundation with Self-balanced Method in the Construction of Large Pile Diameter under Water

以硃山湖北路西延伸段桥梁工程为例,对自平衡法桩基静载试验在水下大桩径桩基工程检测中应用的实施方案、质量控制、结果分析、前景应用进行了探索和实践,并取得了良好的试验结果,为今后在水上试桩,坡地试桩,基坑底试桩,狭窄场地试桩积累了经验。

Taking the project of west extension of Zhu Shan Hubei Road as an example,this paper explores and practices the implementation scheme,quality control,result analysis and prospect application of static load test of pile foundation with self-balanced method in the detection of underwater large diameter pile foundation.Good test results have been obtained,which has accumulated experience for future testing piles on water,on slope,on the bottom of foundation pit and on narrow site.
