摘　　要：为研究现有钢桥面铺装方案评判方法,选取影响铺装方案的21项评价指标作为评判因素集,建立各因素间的层次关系。应用层次分析法和德尔菲法确定各评价指标的权重,从而构建钢桥面铺装方案综合评价模型。基于该模型对某长江公路大桥进行模糊综合评判,确定其优选方案,评判结果与工程实践具有较好的吻合度,可为现有钢桥面铺装方案比选评价及决策提供一定的借鉴和支持。For the study of the evaluation method of service steel deck pavement scheme,21 main evaluation indexes which influence the pavement scheme were selected as the evaluation factors set,and then hierarchical relationship between various factors were established.The weight of each index was determined by applying analytical hierarchy process and Delphi methods.And on this basis comprehensive evaluation model on the scheme of steel deck pavement was established.Based on this model,a Yangtze River Bridge was evaluated by fuzzy comprehensive evaluation and determined the preferred scheme.The evaluation results and engineering practice had a good alignment,which provide certain reference and support for evaluation and decision to select scheme of the service steel deck pavement evaluation and decision.
