长江桥拱座深基坑开挖与防护技术

Excavation and Protection Technology of Deep Foundation Pit of Yangtze River Bridge Arch

香溪长江大桥是比较有代表性的长江大桥,其在建设时同样也面临着较高的施工难度,尤其是在桥梁拱座施工建设时,更是需要采用深基坑处理方式构建,对施工操作提出了更高的要求。以香溪长江大桥施工项目为案例,探讨了在桥梁拱座深基坑开挖以及防护技术应用中需要注意的一些关键要点。

The Xiangxi Yangtze River Bridge is a relatively representative Yangtze River Bridge.It also faces high construction difficulties during construction.Especially in the construction of bridge abutments,it is necessary to use deep foundation pit treatment.Therefore,it is inevitable to put forward higher requirements for construction operations.This paper focuses on the Xiangxi Yangtze River Bridge construction project as a case study,discusses some key points that need to be paid attention to in the excavation of the deep abutment of the bridge arch and the application of protection technology.
