Abstract

With the development of global economic integration, marine bridges have become an important infrastructure for many countries, and will contribute to the rapid development of marine economy. Given that structural types and construction equipment for current bridges can hardly satisfy the requirements for deep-sea bridges, in-depth strategic research on construction technology and equipment for marine bridges shall be conducted. In the aspect of deep-water foundations, research directions of large size, assembly, and intellectualization are proposed for open caisson foundations, assembly foundations, and large-diameter steel pile foundations. As for superstructures of cable-stayed bridges and suspension bridges, the focus of research should be large-segment manufacturing and transportation, automatic alignment for installation, and structural wind-resistance measures for main towers, main girders, and stay cables. In terms of smart construction, comprehensive applied research should be conducted combining an information platform and visualization equipment.
