我国海洋桥梁工程建设正不断向离岸深海长联大型发展，但由于其所处自然环境恶劣、地质与荷载条件复杂，针对海洋桥梁工程全寿命期的健康监测、测量技术、巡检技术、管理与维护，仍存在许多难题亟待解决。本文在总结目前桥梁工程全寿命管理维护存在问题的基础上，针对海洋桥梁提出多参量、高可靠、大容量、长距离的光纤传感健康监测、“天–空–地–海”一体化测量、自动化巡检和智能化管理维护平台等技术及其发展要点，研究各技术要点的重点难点问题和发展方向，探讨海洋桥梁工程全寿命管理维护技术的发展战略目标，为海洋桥梁工程建设和运营安全提供技术支撑。

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.
