摘　　要：研究目的:针对西部复杂艰险地区铁路隧道工程施工安全管理难度高、安全事故发生风险大的问题,本文探讨以安全屏障模型作为阻隔风险源、阻断安全事故发生的有效手段,将提高建设安全管理系统自身的韧性作为确保隧道建设系统安全可靠性能的重要目标。研究结论:(1)基于“4M”事故致因理论建立了铁路隧道工程的安全屏障模型,运用ISM的方法搭建了防御要素结构图;(2)采用距离熵的方法量化数据并计算动态权重,结合静态IIM和动态IIM度量安全屏障模型的韧性水平;(3)建立了安全屏障动态优化系统,划分安全屏障预警等级,确保了系统安全性能;(4)在K2号隧道进行应用,实现安全风险预警和安全隐患排查整改,提升安全韧性水平,实现安全风险控制目标。Research purposes:In response to the high difficulty of safety management and high risk of safety accidents in railway tunnel construction in complex and dangerous areas in the western region,this paper explores the use of safety barrier models as an effective means to block risk sources and prevent safety accidents.Improving the resilience of the construction safety management system itself is an important goal to ensure the safe and reliable performance of the tunnel construction system.Research conclusions:(1)Based on the"4M"accident causation theory,a safety barrier model for railway tunnel engineering was established,and an Input-output Structural Model(ISM)was used to construct a diagram of defense elements.(2)The method of distance entropy was used to quantify data and calculates dynamic weights,and the resilience level of the safety barrier model wais measured by combining static Inoperability Input-output Model(IIM)and dynamic IIM.(3)A dynamic optimization system for safety barriers was established,dividing safety barrier warning levels to ensure system safety performance.(4)The research results can be applied in the K2 tunnel,achieving safety risk warning and rectification of safety hazards,improving safety resilience levels,and achieving safety risk control objectives.
