基于F-AHP法的隧道突涌水风险等级评价
Risk grade evaluation of tunnel water inrush based on fuzzy analytic hierarchy process

为了防治隧道突涌水灾害，基于模糊层次分析法，以云山隧道为例，建立隧道突涌水风险等级指标递阶层次结构模型，确定其突涌水风险等级。研究结果表明：裂隙水、超前地质预报和监控量测是控制云山隧道发生突涌水风险的主要因素；确定云山隧道突涌水风险发生概率等级为4级，云山隧道突涌水风险损失等级为3级，云山隧道突涌水风险等级为Ⅲ级。基于模糊层次分析法的云山隧道突涌水风险等级评价结果与设计阶段安全风险评估报告相一致，表明运用该方法进行隧道突涌水风险等级确定具有一定的合理性和科学性，为今后类似工程提供参考和借鉴。
In order to control sudden water inflow disasters of tunnel, based on the fuzzy analytic hierarchy process and taking Yunshan tunnel as an example, hierarchical structure model was based on established to evaluate risk grade in tunnel sudden water inflow. The results show that the central factors controlling sudden water inflow in Yunshan tunnel are crack water, advance geological forecast and monitoring measurement. The risk grade of possible dangerous will take place is 4th level, the loss seriousness is 3th level and the risk rating of Yunshan tunnel sudden water inflow is 3th level. The evaluation results for the risk level of Yunshan tunnel sudden water inflow on the basis of Fuzzy Analytic Hierarchy Process is consistent with the design stage security risk assessment report, which illustrates that this method has a certain rationality and science, and it can provide reference to the similar engineering in the future
