摘　　要：隧道施工过程中常会发生突水涌泥灾害,严重影响隧道施工安全,因此对灾害风险进行评估具有重要意义。本文以2022年北京冬奥会重大交通保障工程延崇高速公路玉渡山隧道为工程背景,采用调查问卷咨询现场技术指导和专家组成员,建立各层次影响因素判别矩阵,采用AHP-Fuzzy法对隧道发生突水涌泥的风险进行分级评估。研究结果表明:(1)综合23种因素建立了隧道突水涌泥风险评估层次结构模型;(2)影响隧道突水涌泥的主要因素为围岩特征和水文地质条件;(3)得出玉渡山隧道ZK18+510~670段突水涌泥风险等级为IV级,为高风险突水涌泥地段。本文研究结果与工程实际情况基本相符,可为相关隧道工程的突水涌泥风险分级工作提供一些参考。Water inrush and mud flooding often occur during tunnel construction,which will seriously affect the safety of tunnel construction,so it is very important to carry out risk assessment for this type of disaster. This paper takes the 2022 Beijing Winter Olympics major traffic security project-Yanchong Expressway Yudushan Tunnel as the engineering background,and uses the questionnaire to consult the on-site technical guidance and the experts to establish the judgment matrix of the influencing factors at various levels, evaluates the risk of water inrush from the tunnel by using the method which combines hierarchical structure model and fuzzy mathematics. The research indicates that:(1) a comprehensive hierarchical model for risk assessment of tunnel water inrush is established by analyzing 23 factors;(2) surrounding rock characteristics and hydrogeological conditions are the main factors leading to water inrush in tunnels;(3) it is concluded that the risk level of water inrush from the ZK18+ 510 ~ 670 section of Yudushan Tunnel is Grade IV,which is assessed as a high-risk water inrush. The evaluation results are basically consistent with the actual situation of the project,and the research results can be a reference for the risk classification of water inrush in the relevant tunnel engineering.
