高速公路隧道运营安全综合评价研究

Study on Comprehensive Evaluation of Operation Safety of Expressway Tunnel

为了降低高速公路隧道运营的安全事故,根据模糊综合评价理论,提出主观与客观、静态与动态相结合,以定量分析为主的全面综合考虑高速公路隧道运营安全各个影响因素的综合评价方法,采用Delphi法和AHP法建立了高速公路隧道运营安全综合评价指标体系对其安全进行评价,采用平均加权法对评价因素的各项指标进行量化处理,从而对高速公路隧道运营安全状况做出科学合理的分析和评判。最后,通过对陕西省某一高速公路隧道进行了实践验证。结果表明,该综合评价体系能较真实地反映此隧道的安全状况,证明评价方法是可行的。

In order to reduce the accidents in operation of expressway tunnel,based on the fuzzy comprehensive evaluation theory,combining subjective with objective and static character with dynamic character,a comprehensive evaluation method that stressing on quantitative analysis and comprehensively considering different influencing factors of expressway tunnel operation safety was put forward.An evaluation index system of expressway tunnel operation safety was established by using Delphi method and analytical hierarchy process（AHP）.Each evaluation index was quantified and digitized by weighted average method to make a scientific and reasonable analysis for operation safety in expressway tunnel.The presented method was verified by practice in an expressway tunnel of Shaanxi Province.The result shows that the evaluation index system could reflect operation safety of expressway tunnel and the presented method is effective.
