摘要
某大桥为一座7×60 m的空腹式钢筋混凝土箱板拱桥,运营至今已20余年。结合工程实例介绍公路旧桥全桥鉴定内容,分析病害产生原因,并提出维修建议。对维修加固后的桥梁进行荷载试验以检验维修加固效果。
A certain bridge discussed in this paper is a 7 × 60-m span open spandrel reinforced concrete box and plate arch bridge that has been in operation over 20 years up to date. In this paper, by way of specific examples,the inspection and assessment tests of the overall old highway arch bridge are presented, the causes leading to the deteriorations in the bridge are analyzed and proposals for repairing and strengthening of the bridge are made. Eventually, load tests for the repaired bridges are conducted in order to evaluate the effect of strengthening of the bridge.
