武汉长江隧道盾构始发井深基坑施工技术

武汉长江隧道工程盾构始发井为深基坑工程,在长江附近、地质条件复杂、地下水位较高的武昌地区修建大跨、长距离的深基坑难度极大。结合工程实践,详细阐述了武汉深基坑施工技术,包括连续墙的施工、基坑降水、基坑开挖、主体结构施工以及监控量测等施工技术,对今后类似工程的修建有一定的指导意义。

Deep Base Hole Construction Technique of Initial Sending Well of Wuhan Yangtze River Tunnel

The initial sending well of Wuhan Changjiang River Tunnel is a project of deep base hole. It is difficult to build large deep base hole near the Yangtze River, under complex geological conditions and a higher underground water level of Wuchang district. In light of engineering practice, the author idtroduces the deep base hole construction technology adopted in the city of Wuhan, and the focus is on the construction of a continuous wall, base hole precipitation, base hole excavation, construction of the main structure, control measurements and other construction technology.
