在回顾世界跨海通道发展历程的基础上,总结了铁路轮渡、跨海大桥、海底隧道、桥隧组合等跨海工程形式的优缺点。分析了国内外代表性跨海工程的技术、投融资和运营模式等进,展望了跨海工程的发展趋势,提出中国跨海工程建设应加强工程项目的前期调查、研究和设计,重大跨海工程由国家作为建设主体,前期研究开发经费由国家财政予以支持,对工程方案、投融资模式等结合工程所在地情况进行科学决策。
On the basis of reviewing the history of the trans-sea passage in the world, the advantages and disadvantages of cross-sea engineering forms such as railway ferries, sea-crossing bridges, undersea tunnels and bridge-tunnel combinations are summarized. The paper analyzes the technology, investment, financing and operation mode of representative cross-sea projects at home and abroad, and looks forward to the development trend of cross-sea projects. It is suggested that preliminary investigation, research and design of construction projects should be strengthened in China’s cross-sea project construction. Major cross- Projects by the state as the main body of construction, research and development funding for the previous period by the state finance to support the engineering programs, investment and financing mode combined with the project location for scientific decision-making.
