摘要
面对一座需要加固的梁式桥梁,决策者需要从影响加固方案的各因素做出判断选择合适的加固方式。采用FHAP模型作为综合评价体系,并鉴于文献常见模型的弱点,引入G1-序分析法计算指标权重向量对其进行改进。通过一座20m钢筋混凝土T梁桥的分析表明,该方法可起到较好的辅助决策作用。
When a beam type bridge meets strengthening,decision-makers need to judge and select suitable strengthen method from effect factors. This paper set up a comprehensive assessment system with FHAP,and applied rank analysis based on G1 method,which can improve the common imperfection of other models in previous papers,to calculate the weighting values. Then the analysis of strengthening of a 20 meters ferroconcrete T-beam bridge also indicates that this method is very helpful for aid decision making.
