摘　　要：文章通过分析现行桥梁检测诊断方法存在的问题,结合在役桥梁诊断的指标体系和等级标准,提出利用熵权法确定诊断指标权重的思路,引入灰色多层次模糊综合诊断方法,建立了灰色熵权法的在役桥梁诊断的多层次模型,并运用可靠度进行检验。通过实例分析,证明了该方法能够更客观地反映在役桥梁的技术状况,具有较好的可操作性和实用性,对更加科学合理地评价在役桥梁诊断的结果具有现实的参考价值。Through the analysis of the problems exist in current bridge inspection diagnosis,the article proposes that by using entropy method to determine the weight of diagnosis indicator,and brings out idea of gray multi-level fuzzy synthetically diagnosis.The multi-level model of the gray entropy method in the service bridge diagnosis is established and reliability test is used.By studying the practice,this method was proved to more objectively reflect the condition of servicing bridge and has good feasibility and usability.This method also offers a good reference to the evaluation for the servicing bridge diagnosis.
