大跨径钢桥面铺装设计理论与方法研究

结合南京长江第二大桥、舟山桃夭门大桥、润扬长江公路大桥和杭州湾大桥等大型桥梁桥面铺装的研究与设计 ,对大跨径钢桥面铺装设计理论与方法 ,包括铺装材料与结构、钢桥面铺装体系受力特性、疲劳特性、热塑性沥青混合料铺装车辙、设计指标、轴载换算方法、设计方法等关键技术进行系统的分析与研究 ,研究成果已在多座大跨径钢箱梁桥面铺装设计和铺装工程中应用

RESEARCH ON THEORY AND METHOD OF LONG-SPAN STEEL BRIDGES DECK SURFACING DESIGN

Based on research and design of steel bridges deck surfacing for Nanjing Second Yangtze River Bridge, Zhoushan Taoyaomen Bridge, Runyang Yangtze River Highway Bridge and Hangzhouwan Bridge and so on, it is systematic to analyze and research the theory and method of long-span steel bridges deck surfacing design, including surfacing materials and structure, mechanics characteristic of steel bridges deck surfacing, fatigue characteristic, rutting of steel bridges deck thermal-plastic asphalt mixture surfacing, design indexes, axle-load exchanging method and design method. And the research results are successfully applied to many long-span steel-box joist bridges deck surfacing design and surfacing engineering.
