备注

为降低岩溶隧道突涌水的危害,减少人员伤亡及经济损失,采用理论分析与实例验证相结合的方法,通过分析各地质因素的影响,构造以地层因素、地质构造、地形地貌、水文地质为一级评价指标,以岩溶化程度、岩层组合等10个因素为二级评价指标的评价体系,并依此建立了岩溶隧道突涌水危险性多级模糊综合评价模型,对齐岳山隧道的2个区段进行了突涌水危险性评价。评价过程中,采用了改进的方法确定各影响因素权重,克服了传统方法需要一致性检验的缺陷,针对各影响因素的不同特点,采用定性与定量相结合的方式分别确定其隶属度。将得到的评价结果与实际施工结果进行比较,结果表明,理论分析结果跟现场实际状况基本一致。

In order to reduce the damage of water inrush in karst tunnels and control the casualties and economic losses,this article built a multilevel fuzzy comprehensive evaluation model to evaluate two sections of the Qiyueshan Tunnel by combining theoretical analysis and verification method.This model was built according to a risk assessment system which had two levels.Each level was made through analysis of each geological factor's influence.First level has stratum factors,geological structures,topography and hydrogeological.Second level has karst degree,rock combination and other eight factors.In the process of evaluation,when it comes to determine the weight of each factor,this article used an improved method to overcome the traditional method's defect which requiring consistency-test.As the difference between each factor,this article also used a combination of qualitative and quantitative manner to determine their memberships.At last,by compared with each other,the evaluation result showed a satisfying conclusion compared with real condition.It's feasible to use multilevel fuzzy comprehensive theory to evaluate water inrush in karst tunnels.
