摘　　要：当前美国的桥梁工程已由建设高峰期转入以维修加固为主的时期,对截止到2006年美国在役桥梁与病害桥梁的统计数据进行了分析,并对自1875年以来美国桥梁倒塌的相关资料进行了统计,并阐述了美国针对旧桥病害及倒塌事故的对策与措施。最后,结合美国的经验教训与工程对策,对我国桥梁建设与养护工作提出了几点建议。Currently the American bridge community focuses mainly on bridge maintenance and strengthening, rather than new bridge constructions. In this paper, statistical data on bridge inventory and deficient bridges up to 2006 are analyzed,and the data of bridge disasters from 1875 are briefly summarized. Furthermore, the countermeasures to bridge deficiencies and disasters taken by the United States are investigated. Finally, suggestions to Chinese bridge construction and maintenance are made from American lessons and experiences.
