【摘要】：桥面铺装是桥梁工程中的关键技术环节,自上世纪90年代以来,我国掀起了一股大跨径桥梁的建设热潮,而这些新建的大跨径桥梁之中,绝大多数均采用了正交异性钢桥面板,这就进一步加快了钢桥面铺装的研究进程,也促成了我国钢桥面铺装事业的发展。针对目前钢桥大量广泛应用的现状,在国内形成一套相对完整的钢桥面铺装成套应用技术已成为亟待完成的课题。世界上最早开展钢桥面铺装研究和实践的国家是德国,随后法国、日本、美国等国家也相继开展了这方面的工作,德国、日本还制定了相应的技术规范。这些国家对钢桥桥面铺装层设计(包括铺装材料与厚度设计)主要采用结合材料试验的经验设计法。纵观各国大跨径桥梁的钢桥面铺装情况,各种铺装材料均有不同程度的应用,有的主张采用厚层铺装,有的主张薄层铺装,且使用效果也各不相同。本文主要以青岛跨海大桥试验桥的施工为基础,合理利用试验设备和施工工艺,对浇注式沥青混凝土桥面铺装技术进行深入探讨。青岛跨海大桥横跨青岛胶州湾,把青岛东、西两个主要城区连接起来。东起主城区308国道,跨越胶洲湾海域,西至黄岛红石崖,路线全长约35.4公里,其中海上段长度26.75公里。青岛侧陆上桥梁5.85公里。红石崖侧陆上段桥梁及道路共0.9公里,红岛连接线长1.9公里,该项目总投资达到99.38亿元。通过调研对比,胶州湾高速公路(青岛至黄岛方向)女姑口大桥与海湾大桥在环境、交通量及荷载等方面较接近,作为桥面铺装试验桥具有代表性,经指挥部与青岛市高管处协商,选择该桥(试验截取长度为600m,宽度5.5m,厚度9cm)。进行实体试验研究。通过工程实际施工过程中遇到的问题,经过仔细的分析和研究,针对施工实际情况,制定了专项施工方案和施工措施。在实事求是的基础上,以科学合理,技术工艺先进可行而又经济适用为原则,结合工程实际有关质量、工期、安全、环保等要求进行编制施工组织计划。实施项目法施工的管理模式,通过对技术、方案、劳务、设备、材料、资金、信息、时间与空间条件的优化处置,实现工期、成本、质量及社会信誉的预期目标效果。坚持专业化组织施工的原则,安排具有丰富施工经验的专业队伍承担。依托本次青岛海湾大桥试验桥项目的施工对浇注式沥青混凝土桥面铺装结构与施工工艺参数的研究对具有重大意义。在今后的浇注式沥青混凝土桥面铺装施工当中,我们吸取国内外先进施工经验,结合相关理论知识和每个具体项目施工的实际情况,优化施工方案,编排合理的施工组织计划,严格执行；同时加强质量控制,使理论知识真正的与工程实践结合起来,发挥其应有的功用。
[Abstract]:Deck pavement is a key technology in bridge engineering. Since -10s, there has been an upsurge in the construction of long-span bridges in China. Among these newly built long-span bridges, most of them use orthotropic steel bridge panels. This further speeds up the research process of steel bridge deck pavement, and also promotes the development of steel bridge deck pavement in China. Forming a relatively complete set of steel deck pavement application technology in China has become an urgent task to be completed. The earliest country in the world to carry out research and practice of steel bridge deck pavement is Germany, then France, Japan, The United States and other countries have also carried out this work one after another. Germany, Japan has also drawn up corresponding technical specifications. These countries mainly adopt the empirical design method of combined material test for the design of deck pavement of steel bridges (including pavement material and thickness design). All kinds of paving materials are applied to different degrees, some of them are used in thick layer pavement, others in thin layer pavement, and the results are different. This paper is mainly based on the construction of the test bridge of Qingdao Sea Crossing Bridge. Reasonable use of test equipment and construction technology is used to discuss the paving technology of pouring asphalt concrete bridge deck. The bridge across Jiaozhou Bay, Qingdao connects two main urban areas of Qingdao east and west, and starts 308 National Road in main urban area from east to west. Across the sea area of Jiaozhou Bay, to the west of Huangdao Hongshiya, the route is about 35.4 kilometers long, of which the length of the sea section is 26.75 kilometers, the length of the Qingdao side of the land bridge is 5.85 kilometers, the length of the bridge and road on the side of the red stone cliff is 0.9 km, and the length of the Red Island connection line is 1.9 km. The total investment of the project is nine billion nine hundred and thirty-eight million yuan. Through investigation and comparison, the Wugukou Bridge of Jiaozhou Bay Expressway (from Qingdao to Huangdao) is close to the Bay Bridge in terms of environment, traffic volume and load. After consultation between the headquarters and the Qingdao City Executive Office, the bridge (the test intercept length is 600m, width is 5.5 m, thickness is 9 cm) is selected to carry out solid test research. Through the practical construction process of the project, the problems encountered are carefully analyzed and studied. According to the actual situation of construction, the special construction scheme and construction measures are formulated. On the basis of seeking truth from facts, taking scientific and reasonable, advanced technology, feasible and economical application as the principle, combined with the actual project quality, time limit, safety, Environmental protection and other requirements for the preparation of construction organization plans. Implementation of the project method of construction management model, through the technology, scheme, labor, equipment, materials, funds, information, time and space conditions to achieve optimal disposal, time, cost, Target effect of quality and social reputation. Adhere to the principle of professional organization of construction, The construction of the experimental bridge project of Qingdao Bay Bridge is of great significance to the study of the pavement structure and construction process parameters of pouring asphalt concrete bridge deck. In the future construction of pouring asphalt concrete bridge deck pavement, We draw on advanced construction experience at home and abroad, combine with relevant theoretical knowledge and the actual situation of each specific project, optimize the construction plan, arrange reasonable construction organization plan, strictly carry out, at the same time, strengthen the quality control, Make the theory knowledge truly combine with the engineering practice, give play to its due function.
