基于AHP-Fuzzy的隧道施工坍塌风险评价

Risk Assessment of Tunnel Construction Collapse Based on AHP-Fuzzy

文中以某高速公路隧道为工程背景,以问卷形式调查并咨询专家组成员,建立影响因素判断矩阵,运用模糊综合评判层次分析法,对隧道发生坍塌风险进行分级评估。研究结果表明,运用21种因素构建隧道坍塌风险评估的层次结构模型,结果符合工程实际情况;工程地质条件和监控测量为造成隧道坍塌的主要因素;隧道K32+790~K32+870段坍塌风险等级为Ⅳ级,为较高风险坍塌地段。文中的研究结果与工程实际情况基本一致,可为相关隧道工程的坍塌风险分级提供一定参考。

This paper takes a highway tunnel as the engineering background,surveys the members of the consulting expert group by means of questionnaires,establishes a judgment matrix of influencing factors,and uses the fuzzy comprehensive evaluation method of analytic hierarchy process to evaluate the collapse risk of the tunnel.The research results show that:the hierarchical structure model of tunnel collapse risk assessment is constructed by using 21 factors,and the results are in line with the actual situation of the project;the main factors affecting the tunnel collapse are engineering geological conditions and monitoring and measurement;the collapse risk of the tunnel K32+790~K32+870 section,The grade is grade IV,which is a high-risk collapse area.The research results of this paper are basically consistent with the actual situation of the project,which can provide a certain reference for the collapse risk classification of related tunnel projects.
