摘　　要：随着路网建设加密以及通道资源的稀缺,桥梁工程建设不断从内陆向近海延伸,高速公路的海上立交将不可避免。近年来,随着我国海上立交工程规模、难度不断提升的同时,在技术上也不断取得新的突破。杭甬高速公路复线滨海互通建成后将标志着我国完全掌握了建造大型海上互通的能力。本文首先总结我国已建成海上立交的成功经验,并分析海上立交建造的发展趋势,然后梳理滨海互通立交施工技术重难点,最后指出复杂海域条件下的海上立交建造技术、快速施工技术和长寿命建造技术是海上立交建造中面临的关键挑战。With the densification of road network and the scarcity of passage resources, bridge engineering projects are continuously extending from inland to offshore, making the construction of offshore interchanges for highways inevitable. In recent years, China has continuously achieved new breakthroughs in the technical difficulty and construction scale of offshore interchange construction. The completion of the Hangzhou-Ningbo Expressway double-track coastal interchange will signify that China has fully mastered the capability to construct large-scale offshore interchanges. In this study, experiences in offshore interchange construction are reviewed first, and the development trend of offshore interchange construction are analyzed. Then, the key and difficult points of the construction technology for the Binhai Interchange are sorted out. Finally, it is pointed out that the construction technology, rapid construction techniques, and long-life construction methods in complex maritime conditions are the key challenges faced in offshore interchange construction.
