新型超薄混凝土铺面在钢桥工程中的应用

Application of New-style Ultrathin Concrete in Steel Bridge Decking

目前我国港口正在使用的大、中型桥梁的桥面都不同程度地存在病害,甚至已经严重影响到正常使用,桥面的后期维护费用大增。通过分析港口桥梁铺面存在的普遍问题,着重探讨钢桥桥面铺装病害的预防改进措施,并结合营口港鲅鱼圈港区某矿石码头的设计和施工实践,提出1种新型的钢桥面铺装结构,可供类似工程参考。

At present, the large and medium-sized bridges being used for the ports in China are damagea up to different extents. Among them, some bridges are even stopped for using, and the maintenance fee of bridge deck is increasing a lot. By analyzing the problems existed in the port bridge decking, we discuss emphatically the improving measures for preventing steel bridge deck from any damage. In addition, combining with the design and construction of Bayu Bay Harbor Mineral Ore Terminal of Yingkou Port, we bring forward a new-style steel bridge decking structure, which will provide references for similar projects.
