摘　　要：现役桥梁拆除方案的评价指标往往涉及多因素和多层次,造成拆除方案难以通过传统决策方法进行科学有效的评价,针对此问题,为了进一步提升方案决策的合规性和合理性,提出采用层次分析法来评价现役桥梁拆除方案。通过对现行规范和工程案例的分析,在综合考量后归纳了6种常用拆除方案和7种主要影响因素,建立了涉及多因素多变量的现役桥梁拆除方案评价模型。为验证评价模型的有效性,将其应用于陕西省西安市的某桥梁拆除工程中,通过评价模型最终选定了分段切割移除的方案;根据全过程各方参建单位的反馈,该方案得到了多数人的认可,进一步验证了评价模型的可靠性和实用性,可为同类项目提供有参考价值的工程案例。The evaluation indexes of existing bridge demolition schemes often involve multiple factors and levels.As a result,it is difficult to conduct the scientific and effective evaluation of the demolition schemes through the traditional decision-making methods.Aiming at this problem,in order to further improve the compliance and rationality of the scheme decision,the analytic hierarchy process(AHP)is used to evaluate the demolition scheme of existing bridges.By analyzing the current regulations and engineering cases,six common demolition schemes and seven main influencing factors are concluded after all things considered.An evaluation model of bridge demolition scheme involving multiple factors and variables is established.To verify its effectiveness,the evaluation model will be used in a bridge demolition project located in Xi'an,Shaanxi Province.Finally,the segmented cutting removal scheme is selected through the evaluation model.According to the feedback of the participating units in the whole process,the scheme has been recognized by the majority of people,which further verifies the reliability and applicability of the evaluation model,and can provide a valuable engineering case for the similar projects.
