摘　　要：提出了桥梁生命周期环境影响评价和对比分析方法,对于不同桥梁的环境影响评价结果采用单位桥长法和单位原材料法进行修正,并应用于武汉市墨水湖大桥和南太子湖大桥.结果表明,在建筑材料生产过程和桥梁施工过程中固体废弃物环境影响最大,在桥梁运营维护过程中全球变暖环境影响显著,南太子湖大桥施工方法较墨水湖大桥更为环保.A life cycle assessment （LCA） framework was developed to evaluate bridge environment impact of bridges. The synthesized environment impact was analyzed in terms of environmental pollution. The Southern Taizi Lake bridge and Moshui Lake bridge in Wuhan were analyzed and compared by introducing unit length method and unit material method. The results show that solid castoff take up the most environment impact in courses of raw materials＇ process and construction, and global warming evidently caused the environment impact during the stage of operation, the construction method of Southern Taizi Lake bridge is better to environment than that of Moshui Lake bridge.
