【摘要】：港珠澳大桥钢桥面铺装工程规模巨大，施工条件复杂，是目前世界上难度最大的跨海钢桥面铺装工程。大跨径钢桥面铺装一直是一个世界性的技术难题，开展钢桥面施工研究，控制港珠澳大桥钢桥面铺装工程的质量具有重要的现实意义。本文以港珠澳大桥施工图设计阶段钢桥面铺装加速加载试验专题研究为依托，通过对港珠澳大桥钢桥面铺装方案设计条件、铺装方案比选、铺装材料性能试验、施工工艺技术、施工质量检验要求等方面开展系统研究工作。论文结合港珠澳大桥实际使用情况，考虑桥面板刚度、温度环境、交通荷载特点三个基本条件，对钢桥面铺装推荐方案进行了分析。通过对防水层施工技术、GMA性能试验及GMA拌和工艺分析，，选定GMA浇注式沥青铺装较适合港珠澳大桥钢桥面铺装。论文通过对浇注式沥青混合料施工工艺研究，研究了拌合工艺对浇注式沥青混合料材料特性和路用性能的影响，分析了施工关键设备研发和GMA施工过程的问题与对策，确定了GMA生产工艺流程。论文通过加速加载试验对铺装材料和铺装结构的研究成果进行可行性验证，试验表明GMA浇注式沥青铺装方案能满足钢桥面铺装高温稳定性和疲劳耐久性要求。最后，论文根据技术规范、工程经验、项目研究成果，制定了港珠澳大桥桥面GMA浇注式沥青铺装施工技术要求和施工质量控制与验收技术标准。
[Abstract]:The steel deck pavement of Hongkong-Zhuhai-Macao Bridge is the most difficult one in the world at present because of its huge scale and complex construction conditions. Long-span steel deck pavement has always been a worldwide technical problem. It is of great practical significance to carry out research on steel deck construction and control the quality of steel deck pavement of HongKong-Zhuhai-Macao Bridge. Based on the special research on accelerated loading test of steel deck pavement of Hongkong-Zhuhai-Macao Bridge during the construction drawing design stage, this paper makes a study on the design conditions of steel deck pavement scheme, selection of pavement scheme, performance test of pavement material, construction technology and technology of steel deck pavement of HongKong-Zhuhai-Macao Bridge. Construction quality inspection requirements and other aspects of systematic research work. Based on the practical use of HongKong-Zhuhai-Macao Bridge and considering the three basic conditions of deck stiffness, temperature environment and traffic load characteristics, the recommended scheme of steel deck pavement is analyzed in this paper. Based on the performance test of waterproof layer and the analysis of GMA mixing process, it is found that GMA pouring asphalt pavement is more suitable for steel bridge deck surfacing of Hong Kong-Zhuhai-Macao Bridge. Through the research on the construction technology of pouring asphalt mixture, this paper studies the influence of mixing technology on the material characteristics and road performance of pouring asphalt mixture, and analyzes the problems and countermeasures of the research and development of key construction equipment and the construction process of GMA. GMA production process was determined. This paper verifies the feasibility of pavement material and pavement structure by accelerated loading test. The test results show that GMA pouring asphalt pavement can meet the requirements of high temperature stability and fatigue durability of steel bridge deck pavement. Finally, according to the technical specifications, engineering experience and project research results, the paper formulates the technical requirements, construction quality control and acceptance technical standards for GMA pouring asphalt pavement of the bridge deck of HongKong-Zhuhai-Macao Bridge.
