随着桥梁工程向深水环境拓展，永久性浮式桥梁结构日益受到国内外学者的关注。该文系统梳理了世界范围内具有代表性的永久性浮式桥梁工程案例，归纳了已建永久性浮式桥梁工程的结构体系，并针对永久性浮式桥梁的力学特性、施工流程和特殊构造相关研究和应用进展进行了介绍，最后从工程经济性、环境适用性的角度对永久性浮式桥梁的发展前景进行了分析。研究表明：永久性浮式桥梁结构在世界范围内获得了一定的工程应用，形成了连续浮箱和离散浮箱两种主要结构体系，在深水条件中显示出了优越的工程经济性。通过深化研究论证，永久性浮式桥梁结构有望在深水跨越工程中获得推广。
As the bridge construction goes forward to the deep-water environments, the permanent floating bridge structures have attracted more and more attention from international scholars. The project cases of worldwide representative permanent floating bridges were presented. The structural systems of the built permanent floating bridges were summarized. The research and application advances regarding the mechanical features, the construction process, and the special configurations of the permanent floating bridges were introduced. Finally, from the perspectives of the engineering economy and environment applicability, the development prospect of permanent floating bridges was analyzed. The research shows that the permanent floating bridge structure has been applied in engineering around the world and has two types of structural systems, which are the continuous pontoon system and the discrete pontoon system. The permanent floating bridges adopted in deep-water environments have shown superior engineering economy. Based on further research and verifications, the permanent floating bridge structures can be applied in deep-water crossing projects.
