跨海桥梁深水设置基础建造技术进展

Overview on Construction Techniques for Deep-water Placed Foundation of Sea-crossing Bridge

设置基础是能够较好适应恶劣海洋环境并成为大跨度跨海桥梁首选的一种基础形式,但在国内的应用和研究还很少。通过对国内外主要跨海桥梁的深水设置基础建造技术的现状进行分析,探讨了我国跨海桥梁深水设置基础技术发展需要在设计理论、大型施工装备、施工技术方面进行深入研究掌握的关键技术,以期对我国日后跨海桥梁在深海、厚软土、强震、强风浪、急流等复杂恶劣环境下桥梁基础的设计和施工有所借鉴。

The installation foundation is a kind of basic form which can adapt well to the negative marine environment and become the first choice of long-span bridges across the sea, but it has been seldom applied and studied in China. Through the analysis on present situation of deep-water placed foundation construction technology of the main sea-crossing bridges at home and abroad, in this article, the key technologies in the design theory, large construction equipment and construction technology for the development of the basic technology of the deep-water bridge in our country have been discussed, in order that which could be used as reference to the design and construction of bridge foundation in deep sea under complicated and difficult environment, such as thick soft soil, strong earthquake, strong wind wave and jet stream and so on.
