摘要
为合理评价桥梁的运营安全性状况,阐述了模糊层次分析法的基本原理,分析了其与传统层次分析法的不同之处,介绍了模糊层次分析法的一般分析步骤,建立了基于层次分析法的桥梁安全状态多级模糊评估数学模型。结合某大桥实际检测工程,通过对现场检测数据的分析,计算了各个监测指标的权重,进而对其安全运营状况进行了综合评估,为该桥运营期的安全养护提供理论依据,也为模糊层次分析法在实体工程中的应用提供参考。
To be reasonably evaluated the situation of operation of the bridge security, described the basic principle of fuzzy AHP, analyzed its difference from traditional AHP, introduced the general analysis steps of fuzzy AHP, established based on the AHP of state of the bridge safety assessment of multi - stage fuzzy mathematical model. Combined with the actual testing of a Bridge Project, through analyzing the field testing data, calculated the weight of each monitoring indicators, thus conducted a comprehensive assessment of condition of its security operations, to provide a theoretical basis for the safety of the bridge maintenance operations, but also for the fuzzy analytic hierarchy process in the entity reference for engineering application.
