基于AHP可拓综合方法的公路隧道安全等级判定研究

Research on safety level of highway tunnel based on AHP-Extension synthesis method

研究了公路隧道安全现状的评价体系,并应用可拓集理论、层次分析法和有关隧道安全评价的专业知识,将可拓集理论与安全评价相结合,建立基于可拓学的公路隧道安全评价分析的物元模型。对辽宁阜新大巴沟隧道运用了这种新的安全评价方法,实践表明:基于AHP可拓综合方法的公路隧道安全评价方法可以准确反映公路隧道的安全等级。

The related highway tunnel safety assessment systems are researched. The extension set theory,the ana-lytic hierarchy process and the professional knowledge of tunnel safety assessment are applied. Extension set theory with the combination of safety assessment,the matter-element model of road tunnel safety assessment analysis is constructed based on extenics. Daba tunnel in liaoning fuxin is as an example to be evaluated by this method. Ap-plications show that safety assessment of the highway tunnel based on AHP-extension synthesis method can accu-rately reflect the security level of highway tunnel.
