通过对近十年来公路桥梁工程建设、运营情况的调查、分析,发现小箱梁上部结构、桥面连续结构、桥面防水等方面存在一些技术问题。经过研究、分析提出了具有针对性的解决方法和改进措施,供今后工程设计、施工参考,以确保工程的可靠性和技术经济的合理性。 Through the investigation and analysis of the construction and operation of the highway bridges and bridges in the past ten years, some technical problems have been found in such aspects as the superstructure of the small box girder, the continuous structure of the bridge deck and the deck waterproofing. After research and analysis, we put forward targeted solutions and improvement measures for the future engineering design and construction reference to ensure the reliability of engineering and technical and economic rationality.
