一种桥梁质量后评价的方法

桥梁建成通车后的质量评价是一个非常重要的环节,为评价桥梁质量,建立了基于可拓层次分析法的桥梁质量后评价模型,并以丹江河2号大桥为实例进行评价。用模型评价丹江河2号大桥评价结果为良,与定性分析结果吻合,和现场调查情况一致。该方法有效避免了传统层次分析法中的大量试算工作,考虑了人们判断的不确定性和决策者的实践经验。可拓层次分析法减少主观性对评价结果的干扰,使评价结果更符合客观实际。

Post-evaluation for Bridge Quality Based on Extent AHP Method

The post-evaluation for bridge quality is a very important step in bridge engineerings.Based on the extensible AHP method,the model for post-evaluation of bridge is set up,and used for evaluation of No.2 bridge in Danjiang River.The model can avoid a great deal of trail calculations, and by using this model,the fuzziness of people's judgment and engineering experiences of many experts are taken into account.The application results show that this method has a good accordance with the reality,it is clear in conception and easy to be put into practice.
