Assessment Method Of Maintenance Management For Highway Bridge Based On The Fuzzy Analytic Hierarchy Process

In recent years,China’s expressway has developed rapidly.Increasing heavy loads and strong traffic flow have caused various diseases to the operation of highway bridges.The causes of the expressway bridges diseases are complex,including congenital deficiencies in construction and design,as well as the reasons for improper decision-making in the maintenance process.In practical projects,if an effective evaluation method of bridge maintenance management can be established to provide scientific decision-making for the maintenance work during the bridge operation period,malignant accidents can be effectively avoided,and economic losses and adverse social impacts can be reduced.Based on the theory of Fuzzy Analytic Hierarchy Process(FAHP),this paper establishes a Fuzzy Hierarchy Model for the Maintenance Management of Expressway Bridges from four aspects: the status quo of bridge maintenance at home and abroad,the overview of the maintenance management of Expressway bridges,the evaluation methods of maintenance management and the application of examples.First of all,review the maintenance and management status of bridges in foreign and domestic countries,and learn about the main focus on the assessment of bridge technology status,but there are few researches on the evaluation model of highway bridge maintenance management.According to the research summary,the indicators affecting the maintenance and management of expressway bridges are summarized,and the list of impact indicators is summarized to facilitate the establishment of management models later.Then,the fuzzy AHP is used to establish the influencing factors,analysis and evaluation system of highway bridge maintenance management.AHP analyzes the weight of the underlying scheme indicators,and the comprehensive evaluation uses fuzzy theory to achieve the goal,and gives the high speed based on fuzzy analytic hierarchy process.Multi-indicator assessment process for highway bridge maintenance management.Finally,applying the specific case to apply the idea of this article in practice engineering,verify that the highway bridge maintenance management evaluation system constructed in the text is complete,the evaluation index is hierarchical,systematic,and the operation is convenient,and it is operable in practical applications..According to the highway bridge maintenance management evaluation system,the construction investor can understand the importance of the influencing factors of the highway bridge maintenance management,and then formulate corresponding targeted maintenance management measures.
