海洋桥梁工程施工技术及装备发展研究

Development of Construction Technology and Equipment for Marine Bridges

随着全球经济一体化战略的实施,海洋桥梁已成为各国基础设施重要的组成部分,这条绚丽的蓝色纽带也将带动海洋经济的快速发展。目前,已建成的海洋桥梁结构形式及施工装备还远不能满足桥梁向纵深海域发展的需要,为储备高端关键技术,迫切需要深入海洋桥梁施工技术及装备发展战略研究。在深水基础方面,着重对沉井基础、设置基础及大直径钢桩基础的大型化、装配化及智能化提出研究方向;在海洋桥梁的斜拉桥及悬索桥上部结构方面,就主塔、主梁及索束的结构形式及施工方法重点研究大节段制造运输、自动调整对位安装、结构抗风措施等;在智慧建造方面,提出结合信息化平台及可视化装备进行综合应用性研究。

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.
