摘　　要：在获取在役桥梁加固经济性主要影响因素的基础上,利用层次分析法的递推层次结构,构建了最底层、中间层以及最高层的在役桥梁加固经济性评估模型,同时结合权重修正技术和模糊数学理论,最终获得了在役桥梁加固经济性的评估方法。经实践检验,在役桥梁加固经济性评估结果能较好地指导桥梁管养工作者对服役桥梁采取安全、有效、合理的处置决策,具有较好的应用推广价值。In this paper, it is on the basis of gaining the main influence factors of strengthening economy for in-service bridge, using recursive hierarchical structure of analytic hierarchy process, constructing the assessment models about strengthening economy for in-service bridge in bottom, middle and top levels, combining with weight modify technology and fuzzy mathematics theory, the assessment results strengthening economic state is gained finally. By practical test, it can discriminant bridge using actuality effectively, and it has been a good guide to maintain in-service bridges safely, effectively and reasonably for maintenance administrative departments, and save a great deal fund for bridge construction
