基于模糊层次分析的单线铁路隧道施工经济性评价

Economic Evaluation of Single Track Railway Tunnel Construction Based on Fuzzy Analytic Hierarchy Process

基于模糊层次分析法,建立单线铁路隧道施工经济性评价指标体系,即运用层次分析法确定单线铁路隧道施工经济性评价指标体系中各指标的权重,再依靠模糊综合评判法将定性和定量指标结合起来对单线铁路隧道施工的经济性等级进行评价,最终建立单线铁路隧道施工的经济性评价等级和分级标准,并将其运用于单线铁路隧道——云南某隧道工程。结果表明:云南某隧道施工的经济性评价等级为Ⅲ级,即"一般"。

Based on the fuzzy analytic hierarchy process,this paper establishes the economic evaluation index system of single track railway tunnel construction,that is,determines the weight of each index in the economic evaluation index system of single track railway tunnel construction by using the analytic hierarchy process,and evaluates the economic grade of single track railway tunnel construction by combining the qualitative and quantitative indexes with the fuzzy comprehensive evaluation method.Then,introduces the economic evaluation grade and classification standard of tunnel construction,and applies it to a single track railway tunnel in Yunnan.The results show that the economic evaluation grade of a tunnel construction in Yunnan is grade III,that is“general”.
