大跨径桥梁钢桥面铺装设计

Design of deck pavement for long-span steel bridges

由于大跨径钢箱梁桥面铺装的使用条件、施工工艺、质量控制与要求的特殊性,因此对于特定的桥梁的桥面铺装均需作针对性的专题研究,以保证铺装设计和施工成功。总结了作者近10年对大跨径钢桥面铺装设计理论与方法设计的研究成果,包括铺装材料与结构、钢桥面铺装体系受力特性、疲劳特性、设计指标、轴载换算原则与方法、铺装体系整体优化设计方法、工程实施等技术,研究成果已在南京长江第二大桥、南京长江第三大桥、润扬长江公路大桥、苏通长江大桥和杭州湾大桥等10多座大型钢箱梁桥桥面铺装设计和铺装工程中应用。

For long-span steel bridge deck pavement, due to the peculiarities of service condition, construction technique, quality control and requirement, special research on the deck pavement should be carried out for each different steel bridge so as to ensure successful pavement design and construction. The research results in the last decade are summarized, including pavement materials and structure, mechanical characteristics of steel deck pavement, fatigue characteristics, design indexes, axle-load equivalent method, optimization design method, and construction technique. The research findings have been successfully applied to the design and construction of steel bridge deck pavement for more than ten long-span steel bridges, such as the Nanjing Second Yangtze River Bridge, the Nanjing Third Yangtze River Bridge, the Zhoushan Taoyaomen Bridge, the Runyang Yangtze River Highway Bridge, the Sutong Yangtze River Bridge and the Hangzhou Bay Bridge.
