随着公路和市政建设事业的发展,近年来城近郊区新建和扩建了大量的桥梁,这些桥梁的主体结构设计合理,施工质量优良,外观各具特色,反映了当代的设计与施工水平。但是,对于一些不直接影响安全使用的设施和细部构造,设计和施工单位往往都没有给予足够的重视,以至近年来在桥梁上经常出现一些影响使用性能的通病。 With the development of highways and municipal construction, a large number of bridges have been newly built and expanded in recent years in suburban areas of the city. The main structure of these bridges has been designed reasonably with excellent construction quality and distinctive appearances, reflecting the contemporary design and construction level. However, design and construction units often fail to pay sufficient attention to some facilities and details that do not directly affect the safe use of the bridge. As a result, some common problems affecting the performance of the bridge often occur on the bridge in recent years.
