岩溶隧道运营期突涌水综合处治方法研究

RESEARCH ON COMPREHENSIVE TREATMENT METHOD OF INRUSH WATER IN KARST TUNNEL OPERATION PERIOD

江西南石壁隧道岩溶区段在运营期间多次发生突涌水病害,严重威胁隧道稳定及行车安全。为根治岩溶区隧道运营期突涌水问题,总结了南石壁隧道历年突涌水病害特征,结合岩溶水分布信息,建立了衬砌结构力学模型,揭示了隧道运营期间的突涌水机理,并提出了岩溶隧道运营期突涌水综合处治方法。

In the karst section of the Nanshibi Tunnel in Jiangxi Province, water inrush disease occurred many times during the operation period, which seriously threatened the stability of the tunnel and the safety of driving.In order to solve the problem of water inrush during the operation of tunnels in karst areas, the characteristics of water inrush in Nanshibi tunnel over the years were summarized, combined with the distribution information of karst water, a mechanical model of lining structure was established, the mechanism of water inrush during tunnel operation was revealed, and the karst tunnel was proposed. Comprehensive treatment methods for water inrush during operation period. This comprehensive treatment method could effectively control the water inrush disease of tunnels during the operation period of karst area, and provided a reference for the treatment of similar projects.
