Abstract Water inrush is a serious geological disaster in tunnel. Due to the complexity of geological conditions, large-scale water inrush is prone to occur in tunnel through water-rich fault during construction. Based on the comprehensive analysis of influencing factors, 8 evaluation indexes and the corresponding grading criteria are put forward to assess the risk of water inrush, and the risk of water inrush is divided into 4 levels. Synthesizing the standardization process and the analytic hierarchy process (AHP), a novel Cloud model is established to assess the risk of tunnel water inrush. The model is applied to the Longjinxi Tunnel to assess the risk level of water inrush. It is proved that the assessment results of the tunnel through water-rich fault is consistent with the actual situation, which verifies the reliability of evaluation model.

基于AHP-Cloud模型的隧道富水断层突水风险评估

摘要 突水是隧道内严重的地质灾害。由于地质条件的复杂性，隧道在施工过程中容易通过富水断层发生大规模突水。在综合分析影响因素的基础上，提出8项评价指标及相应的分级标准对突水风险进行评估，将突水风险分为4个等级。综合标准化过程和层次分析法（AHP），建立了一种新的云模型来评估隧道突水风险。该模型应用于龙津溪隧道突水风险等级评估。证明隧道穿越富水断层的评价结果​​与实际情况相符，验证了评价模型的可靠性。
