摘要: 针对现有养护规范中桥梁评估部分部件划分不全、权重计算粗糙等缺陷,建立了钢管混凝土拱桥递阶层次模 型,并运用基于指数标度的层次分析法计算了部件权重; 将部件的设计承载能力与缺损状况作为安全评估指标,结 合结构层次分析模型与部件权重,建立了完善的钢管混凝土拱桥安全评估指标体系; 运用Visual Basic 语言开发了 钢管混凝土拱桥安全评估系统。将该评估系统运用于浙江省三门健跳大桥的安全评估中,结果表明: 该系统能够 准确、快速的评估结构的安全性,有效的减少了桥梁评估工作量。

Abstract: Aiming at the defects in the current bridge evaluation parts of maintenance codes,for instance,the imperfect classification of components and rough calculation of weight,a hierarchical structure model of CFST arch bridge is established, and the analytic hierarchy process method based on exponential scale is used to calculate components weight. The designing load-bearing capacity and distress condition are used as indexes of safety evaluation and the index system for CFST ( concrete filled steel tubular) arch bridge safety evaluation is established,associating with hierarchical structure model and components weight. A CFST arch bridge safety evaluation system is exploited by using Visual Basic language. The safety evaluation system is applied to evaluate the safety of Sanmen Jiantiao Bridge in Zhejiang province. The results show that the proposed system can evaluate the safety of structure accurately and quickly,meanwhile,it can effectively reduce the workload of bridge evaluation.

Key words: CFST arch bridge, safety evaluation, analytic hierarchy process, exponential scale, load-bearing capacity, distress condition, evaluation system
