在公路隧道运营安全管理体系特征分析的基础上,将失效概率分析与可靠度理论引入长大公路隧道运营安全管理体系的分析中,提出了综合评判等级的概念,认为运营安全状况评价等级和运营安全管理体系失效概率(或可靠度)共同决定着长大公路隧道运营安全综合评判等级的状况,并阐释了运营安全管理体系失效概率和可靠度含义,构建了失效分析模型,并给出了失效概率和可靠度计算方法。最后,针对长大公路隧道运营安全管理体系,提出了可靠度控制标准和综合评判等级划分标准,并给出了实例分析。 Based on the analysis of the characteristics of highway tunnel safety management system, the failure probability analysis and reliability theory are introduced into the analysis of tunnel safety management system of Chang-Tai Highway. The concept of comprehensive assessment grade is put forward. The assessment of operational safety status and operation The probability of failure (or reliability) of safety management system jointly determines the status of the comprehensive evaluation level of operation safety of the highway and explains the failure probability and reliability of the operation safety management system. The failure analysis model is constructed and the failure Probability and reliability calculation method. Finally, in view of the highway safety management system for long tunnel, the standard of reliability control and the grade of comprehensive evaluation are put forward, and an example is given.
