水下隧道衬砌结构服役安全及其保障对策思考
Service Security of Underwater Tunnel Lining Structures and Corresponding Guarantee Countermeasures
摘要
Abstract
This paper analyzes four aspects of the safety problems in tunnel lining structures: design and construction, environmental erosion, sudden natural disasters, and sudden accidents. A survey of underwater tunneling such as the Huangpu River's cross-river tunnel and the underground traffic tunnel in Shanghai was carried out, and the status quo of China's underwater tunnel lining struc-ture was analyzed. Based on these analyses, countermeasures guaranteeing the long-life security of underwater tunnel structures are being sought regarding tunnel construction, structural performance degradation, sudden natural disasters, and sudden accidents. These countermeasures are being sought to effectively protect and ensure the service performance of the tunnel structures during their entire life cycle. These security measures can ensure the safe performance of the structure during its entire life cycle, even under long service times. This research can serve as a reference for enhancing the structural security of underwater tunnels and other major tunnel struc-tures.关键词
