【摘要】 隧洞工程的施工条件是非常复杂的，并且存在的不稳定因素比较多，安全隐患很大。传统的经验型安全管理已不能适应现代化管理的需要，所以产生了现代化的科学管理方法——安全系统工程。本文从介绍安全系统工程的概念入手，侧重论述了系统安全分析、系统安全评价和安全决策。在论述系统安全分析方法时，主要论述了事故树分析法。事故树分析方法主要是根据发生的顶上事件，逐步向下分析，通过对发生的原因进行布尔运算，找出事故发生的主要原因。在论述系统安全评价时，主要论述了打分法和模糊综合评价法，打分法针对在某种环境下的安全性，进行子系统安全评价。模糊综合评价是运用模糊数学的知识进行系统安全评价，所评价的系统可以是一个大系统，也可以是一个小系统。在论述安全决策时，主要论述了层次分析法，层次分析法主要是根据专家经验，给出各因素的相对重要度组成判断矩阵，计算各方案措施的相对重要度，进行方案优选，进行决策。 论文的实证研究，选取的是隧洞工程。因为隧洞工程是地质条件最复杂的工程之一，对隧洞的安全控制采用安全系统工程是非常必要的。在隧洞安全系统工程中，采用事故树分析法进行安全分析，采用模糊综合评估法进行系统综合评价，采用层次分析法进行安全决策，取得了良好的效果。 安全系统工程是一门新兴的科学，我们应积极推广它的使用，它是安全管理发展的方向和目标。更多还原

【Abstract】 Constructing condition of tunnel engineering is very complicated ,and the variable factor is much more ,and the past experiencing safety management are not adapted to requirement of modern management ,so the modern science management method -system safety engineering-come into being .This thesis dissertate it from the concept of system safety engineering ,emphasized particularly on system safety analysis ,system safety appraise and safety decision-making . While dissertating system safety analysis method ,emphasizejd particularly on FTA .FTA is the method basing on occurred the top matter ,analyzing from top to below ,processing Boolean operation ,and in the last find out the mostly reason of faulty .While dissertating system safety appraise, emphasized particularly on DAFEN method and fuzzy integrated appraise method .DAFEN method just is used in sub-system and aimed at safety in some environment .fuzzy integrated appraise method process appraise to system safety using the knowledge of fuzzy mathematic which may be a great system or little system .While dissertating s safety decision-making , emphasized particularly on AHP which possess of the relative importance degree basing on experience of expert ,constituting judgment matrix .calculating importance degree of every project .processing project-electing and decision-making.The ultimate aim of method dissertating is put into use Basing on experience in engineering ,tunnel engineering is one of complicated geological condition among engineering ,so it is essential to use system safety engineering on controlling safety of tunnel .In application of tunnel safety engineering .We process safety analysis using FTA ,process system integrated appraise using fuzzy integrated appraise .process safety decision-making using AHP ,and obtain favorable effect.System safety engineering is rising science .we should extend it .it is the developmental direction and target of safety management.更多还原
