丽水城区桥梁技术特征分析及养护策略制定

Analysis of Technical Characteristics of Urban Bridges and Formulation of Maintenance Strategies in Lishui

通过梳理丽水市城区112座城市桥梁的基本资料,根据所在桥位、主要交通功能及技术特点把桥梁分为跨江、绕城和城区内三类桥梁,并从三类桥梁的建成时间、设计荷载等级、技术状况和桥型等方面进行分析,结果表明桥梁技术状况与桥型、桥位及设计荷载等级关系明显。在此基础上根据桥梁养护要求从检查频率、养护要求、风险管控,耐久性方面制定不同的养护策略。

By sorting out the basic information of 112 bridge cities in Lishui City,the bridges are divided into three types of bridges across the river,around the city and in the urban area according to the location of the bridge,the main traffic function and the technical characteristics.The level,technical status,bridge type,and other aspects are analyzed and the results show that the technical condition of the bridge is closely related to the bridge type,bridge position and design load level.Different maintenance strategies are formulated by different parameters which include inspection frequency,maintenance requirement,risk management and durability.
