摘　　要：桥梁加固方案比选方法虽较多,但无统一实用的标准,导致实际工程中桥梁加固方案选择存在一定困难。以贵阳市姬昌大桥桥台加固为背景,基于模糊层次分析法提出考虑全面、简单有效的桥梁加固方案比选方法,并对桥台拆除重建方案、桥台注浆加固方案进行评价比选。研究结果表明,基于模糊层次分析法进行桥梁加固方案比选时,可将具有较大主观性和不确定性的定性评价转化为定量评价,得到直观的评价结果,可更准确地反映桥梁实际情况,使桥梁加固决策更科学合理。At present,although there are many methods to compare bridge reinforcement schemes,there is no unified and practical standard,which leads to difficulties in the selection of reinforcement schemes in practical engineering application.Taking the abutment reinforcement of Jichang bridge in Guiyang as the background,based on fuzzy analytic hierarchy process,a comprehensive,simple and effective method for bridge reinforcement scheme comparison is proposed.The demolition and reconstruction scheme of abutment and the grouting reinforcement scheme of abutment are evaluated and compared.The research results show that when comparing bridge reinforcement schemes based on fuzzy analytic hierarchy process,the qualitative evaluation with great subjectivity and uncertainty can be transformed into quantitative evaluation to obtain intuitive evaluation results.It can also more accurately reflect the actual situation of the bridge and make the bridge reinforcement decision more scientific and reasonable.
