公路隧道初步设计阶段风险评估流程及方法研究

Risk Assessment Process and Method Research of Highway Tunnel at Preliminary Design Stage

根据某隧道初步设计阶段的风险评估,结合交通运输厅对隧道风险评估要求,介绍并提出一个具有实际意义的隧道风险评估流程。并采用专家调查法、层次分析法、模糊综合评判法3种方法,创造性提出了隧道风险评估方法。提出了从单一风险事件的分段评估、单一风险事件的整体评估、隧道总体风险评估3个方面进行评估。这样能保证风险评估的可靠性,加强公路隧道工程安全管理,增强安全风险意识,优化工程建设方案,提高工程建设和运营安全性。

According to the preliminary design phase of a tunnel risk assessment,combined with the transportation department to tunnel risk assessment requirements,a practical tunnel risk assessment process is put forward.Combined with the expert investigation method,analytic hierarchy process method,fuzzy comprehensive evaluation method,the tunnel risk assessment methods are introduced creatively.A single risk event segmentation evaluation,single risk events overall assessment,tunnel overall risk assessment are put forward.It can guarantee the reliability risk assessments,strengthen highway tunnel engineering safety management,enhance the risk consciousness,optimize construction scheme,improve construction and operation safety.
