明星桥为七孔小跨径无铰拱桥,1978年建成,由于开裂严重未能交付使用。1983年底对该桥进行了现场观测和承载力试验,提出了加固方案,加固后情况良好。通过对该桥加固方案的讨论和比较,发现用“体系转换法”加固危桥或改造旧桥是一个比较好的方案。 Star Bridge is a seven-hole small-span non-hinged arch bridge, completed in 1978, due to serious cracking can not be delivered. At the end of 1983, the site was observed and the bearing capacity of the bridge was tested. A reinforcement plan was put forward and the situation was good after the reinforcement. Through the discussion and comparison of the reinforcement scheme of the bridge, it is found that it is a better scheme to reinforce the dangerous bridge or transform the old bridge by the “system conversion method”.
