基于模糊评价方法的隧道岩溶突水地质灾害综合预警方法

Research of Comprehensive Warning of Water Inrush Hazards in Karst Tunnel Based on Fuzzy Evaluation Method

为建立隧道岩溶突水地质灾害预警方法,首先建立了岩溶区隧道施工期岩溶突水地质灾害系统,该系统分为预测、预报和预警3个部分,给出了系统各级指标,并选取典型指标建立评价体系。然后针对宜万铁路典型的风险隧道的岩溶突水地质灾害情况,采用了模糊综合评价模型,尝试建立一种隧道岩溶突水地质灾害的综合评估方法。最后结合宜万铁路齐岳山隧道施工实例进行评价,评价结果与实际施工揭示的结果进行了比较,研究结果和实际工程揭示情况一致,结果表明该研究方法可行。

In order to research the water inrush hazards in karst tunnel, a geological disaster system was set up during tunnel construction in karst areas at first. The geological disaster system includes prediction, forecasting and early warning. The typical indicators were selected for the system, the important indicators and weights of the geological disaster in karst tunnel were discussed, and the fuzzy comprehensive evaluation model was used to assess the karst water inrush hazards in the area of some typical risk tunnels on the Yichang-Wanzhou railway. Finally, the fuzzy comprehensive evaluation model was used to assess the situation of geological hazards in Qiyueshan tunnel. The assessment result meets the result of real construction, which shows that the fuzzy comprehensive evaluation model is feasible.
