Key Construction Techniques for Ultra-wide Tunnel Structure in the Weir Section of the Shenzhen-Zhongshan Link
The Shenzhen-Zhongshan Link is a world-class"bridge,island,tunnel and underground interchange"cluster project,and the construction mileage of the tunnel main structure of the weir section on the East Artificial Island is K6+550～K7+030,and the tunnel structure is a double-decked three-span,single-decked three-span,and single-decked four-span box structure,with the overall span of the structure ranging from 46.2 m to 70.684 m.This paper summarizes and analyzes the construction of the main structure of the tunnel in the weir section of the Shenzhen-Zhongshan Link,verifies the feasibility of the construction plan and construction process,and optimizes the process by taking a series of measures such as increasing the waterproofing control measures,optimizing the reinforcing steel engineering process in the special parts,and optimizing the maintenance methods,etc.,and the quality of the structure has been effectively controlled,which is a reference for the similar projects.
