摘要
国内中小城市在70、80年代兴建了许多钢筋混凝土拱桥,这些桥梁设计标准偏低,已影响正常使用功能,必须对旧桥予以鉴定,经过加固、改造方可继续发挥使用功能。
Many reinforcement concrete arched bridges were built in some domestic cities in 1970s and 1980s. The design standard of these bridges was too low to be used normally now. After appraised, strengthened and rebuilt, these bridges can be resumed.
