Core Viewpoint - The Shenzhen Spring Breeze Tunnel, a significant infrastructure project, has officially opened, featuring a unique "single-hole double-layer" design that enhances urban traffic efficiency and integrates land resources [1][2][3]. Group 1: Project Overview - The Spring Breeze Tunnel is a super-large diameter single-hole double-layer shield tunnel, with a diameter of 15.8 meters and a total length of 5,078 meters, including 4,600 meters of tunnel [2][3]. - The tunnel is designed for a maximum speed of 60 km/h and is restricted to small passenger vehicles with a height limit of 3.5 meters [1][2]. Group 2: Engineering Challenges - The project faced significant engineering challenges due to its location in a complex hydrological environment, with the tunnel traversing various geological formations, including soft and hard rock layers and multiple fault zones [3][4]. - The construction site is constrained, surrounded by numerous buildings and utilities, which adds to the complexity and risk of the project [3][4]. Group 3: Technological Innovations - The Spring Breeze Tunnel utilizes the domestically developed "Spring Breeze" shield machine, which is the largest of its kind in China, overcoming several technical challenges related to large-diameter shield construction [5]. - Advanced monitoring systems, including InSAR satellite remote sensing and BIM digital modeling, have been implemented to ensure real-time data support for construction safety and efficiency [6]. Group 4: Recognition and Future Impact - The project has been recognized as one of the "Top Ten Innovative Projects of Central Enterprises in 2018" and has received accolades for its technological advancements [5]. - The opening of the main line of the Spring Breeze Tunnel is expected to alleviate traffic congestion in the area and enhance regional connectivity once the entire tunnel is operational [6].
