嘉陵江特大桥深水桩基施工关键技术探讨

Discussions on Key Technology of Deepwater Pile Foundation Construction in Jialing River Super-large Bridge

嘉陵江特大桥主墩处于季节性流域的河道中,桥梁钻孔桩施工受洪水影响较大,地质清孔较为复杂,在施工过程中不确定影响因素较多,文章针对该工程区域特殊地质和水文情况,对水中桩基施工的关键技术进行了研究。

The main pier of Jialing River Super-large Bridge is located in the waterway of seasonal river basin,the construction of bridge’s bored piles is largely affected by floods,with complex geological hole clearance hole,and there are more uncertain influential factors in the construction process,thus regarding the particular geological and hydrological conditions of this project area,this article studied the key technologies for the construction of underwater pile foundation.
