摘　　要：运用模糊层次分析法对简支梁的各种加固方法确定评价指标的权重及隶属度,采用线性加权综合法作为FAHP评价决策模型,在承载力提高要求不同的情况下选择最佳的加固方法,可以反映综合评价模型对实际工程有很好的参考价值,同时也体现了综合加固在承载力提高程度大情况下的优越性。During the comprehensive evaluation of strengthening methods of concrete beam bridge,the method of FAHP is put forward to decide the importance ratio of the evaluation indexes and qualitative indexes are quantified,then linear weighted comprehensive assessment method is applied to chosen the best strengthening method in different values of improvement of bearing capacity.In this paper a new method is proposed to evaluate the strengthening methods in practical engineering,meanwhile,the superiority of application of comprehensive strengthening methods is indicated.
