摘要: 为深入了解铁路隧道塌方风险,以铁路隧道塌方事故为研究对象,运用解释结构模型(ISM)化技术对从事故中总结的18个风险因素进行层次化分析,找出风险因素间的关系,建立铁路隧道塌方风险因素ISM;通过直接风险因素和中间风险因素求出底层风险因素的加权归一化信息熵。研究得出导致塌方事故的8个底层风险因素为安全管理不到位、地质勘测不力、选择的开挖方式不当、喷混凝土质量达不到要求、闭合成环周期过长、偏压严重、处于不良地质、地下水渗流;其中,地下水渗流、处于特殊不良地质、开挖方式的选择对隧道塌方影响较大。

Abstract: Taking the railway tunnel collapse accident as the research object, the 18 risk factors summarized from the accident were analyzed hierarchically using the ISM technology, the relationship between the risk factors was found out, and the structural model of the risk factors of the collapse of the railway tunnel was established. Eight underlying risk factors leading to landslide accidents were identified: inadequate safety management, poor geological survey, improper excavation method selected, insufficient sneeze quality, long closing cycle, severe bias, poor geological conditions Groundwater seepage. The weighted normalized information entropy of the underlying risk factors was obtained through direct risk factors and intermediate risk factors. It is concluded that the selection of groundwater seepage, special adverse geology, and excavation methods has a greater impact on tunnel collapse and provides ideas for reducing tunnel collapse accidents.

Key words: railway tunnel, landslide, interpretative structural modeling(ISM), information entropy, risk analysis
