摘　　要：为评价隧道突涌水风险,确保施工安全,本文结合工程实例,利用层次分析法和模糊理论构建了隧道突涌水危险性评价模型,并利用P×C分级法确定隧道突涌水危险性等级。实例检验表明:该模型的权值求解方法具操作简单、准确性高等优点,能有效通过一致性检验,且隶属度求解过程有效综合了定性分析与定量评价,保证了分析结果的准确性;同时,该评价模型可定量评价隧道突涌水的危险性等级,且判别结果与现场实测值的判别结果具较好的一致性,验证了该评价模型的可靠性和准确性,为隧道突涌水危险性评估提供了一种有效途径。Assessment the risk of tunnel water inrush is vital to the construction safety.Combining engineering examples,this work constructs an assessment model of tunnel water inrush by using Analytic Hierarchy Process(AHP)and fuzzy theory,and determines the risk level of tunnel water inrush using the P×C classification method.The example test shows that the weight solution method of the model has the advantages of simple operation and high accuracy.It can effectively pass the consistency test,and the process of solving membership degree effectively synthesizes the qualitative analysis and quantitative evaluation to ensure the accuracy of the analysis results.At the same time,the assessment model can quantitatively estimate the risk level of tunnel water inrush,and the theoretical estimates are well consistent with the field measured values,which verifies the reliability and accuracy of the assessment model,and provides an effective way for the risk assessment of tunnel water inrush.
