摘要

针对未来深水海洋桥梁工程建设需求,本文分析了中国海洋桥梁工程技术取得的成就及存在的不足,提出海洋桥梁工程面临的技术挑战主要为"强风浪、强腐蚀、超水深、超大跨"等四个方面,应高度重视环境作用及其组合、结构耐久性、抗疲劳和全寿命设计等理论研究,重点突破超大跨度桥式方案、超深水基础结构形式和快速施工新型结构形式等结构关键技术瓶颈。建议成立国家级海洋桥梁工程技术研究中心,加强科技硬件力量投入及创新人才培养,完善科技奖励机制。
        In this paper, to better satisfy the future demands for deep-water marine bridge engineering, we analyzed the research status of marine bridge engineering in China, and proposed that strong wind wave, strong corrosion, super water depth, and super large span are the major technical challenges faced by the marine bridge engineering. High attention should be paid to theoretical research on environmental effects and their combinations, structure durability, fatigue resistance, and life-time design; and major efforts should be made to overcome key technical challenges such as super-long span bridge schemes, ultra-deep-water infrastructure forms, and new structural forms capable of rapid construction. We proposed to establish a national marine bridge engineering technology research center, strengthen the investment in science and technology hardware, cultivate innovative talents, and improve the science and technology reward mechanism.
