Abstract
Marine bridge engineering in China is continuously developing to the offshore, deep-sea, long-distance, and large-scale directions. However, due to its harsh natural environment and complex geological and loading conditions, there still exist many problems in health monitoring, measurement technology, inspection technology, and maintenance-management for the lifecycle of marine bridge engineering. Therefore, after summarizing the existing problems in lifecycle management and maintenance of bridges, this paper proposes several key technologies for marine bridge development, including health monitoring based on multi-parameter, high-reliability, large-capacity, and long-distance optical-fiber sensing; space–air–ground–sea integrated measurement; automated inspection; and intelligent management and maintenance platforms. Meanwhile, this paper studies the difficulties and development directions of these technologies, and explores development strategies and recommendations for the lifecycle management and maintenance technology of marine bridge engineering, thereby providing technical support for the construction and operation safety of marine bridge engineering.
