摘要
对澄江西路隧道工程泥水平衡盾构推进过程中所遇的施工难点与存在的技术难题进行了剖析。根据工程实际情况,提出了盾构穿越内河浅覆土层,盾构下穿桩基,邻近建筑物保护,盾构进出洞加固等工程中一系列需要注意的问题,并给出了解决问题的建议,为盾构施工的安全快速推进提供了技术上的保障。
Difficulties in slurry balance shield construction of West Chengjiang Road Tunnel are analyzed. Key issues were raised for attention for construction processes including shield crossing shallow covering soil under the river, shield crossing pile foundations, adjacent building protection, tunnel strengthening for shield entering and leaving. Suggestions were provided for these problems, which can help guarantee fast and smooth progress in shield construction.
