公路桥梁加固方法简述
【摘 要】随着公路事业的蓬勃发展, 公路的通行能力和服务水平进一步提高和改善。作为交通行业, 不仅要积极建设新路、新桥, 还要对旧路线进行改造。在旧路改造中, 突出的问题是建国以来特别是60-80年代, 修建的许多低标准桥梁能否利用, 这些旧桥若都要拆除重建, 国家不仅要花费大量的投资, 而且对环境也会造成污染。这就使得旧桥加固、维修更加重要。旧桥加固、维修既能节约大量投资, 又能收到良好的社会经济效益, 消除交通安全隐患, 提高公路等级及通行能力和服务水平, 但对旧桥加固的研究与实践是一项非常庞大与复杂的工作。由于历史和资金的限制本地区, 大部分二十世纪六、七十年代甚至五十年代修建的桥梁仍在运行之中, 因其设计荷载标准偏低, 再加上当时技术水平限制, 这些桥梁已成为交通运输中的潜在隐患。对于这些旧桥若全部推倒重建, 既不科学、更不现实。当前, 许多旧桥加固过程中, 还存在着原始资料、施工、竣工图纸不全。各种情况因桥、因地不同而异, 又无现成可遵循的旧桥加固技术规范, 这就使得旧桥加固技术的探索与应用更加艰巨。本文根据近年来所进行的旧桥加固实际情况, 介绍了几种旧桥加固维修方法。
