摘要
江南工作井主体结构采用明挖逆作法施工,基坑开挖深度近30m,基坑开挖至临界深度后,坑底面临承压水突涌的威胁。文章详细叙述了钱塘江边水文地质条件下,江南工作井围护结构的施工以及基坑开挖面临承压水的风险所采取的技术措施。
The open-cut inverse construction method is adopted in the main structure of Jiangnan working well. The excavation depth is about 30 meters and inrushing confined water is under threat after critical depth. Thus, enclosure structure construction of Jiangnan working well and technology measures about confined water are introduced in this paper.
