摘要
长凼子隧道横穿长江支流大溪河分水岭——齐耀山复式背斜,为非单一碳酸盐岩溶区。区内岩溶及岩溶水受自然地理、地形地貌、地文期、地层岩性、构造地质控制,岩溶发育,岩溶地下水丰富,给隧道施工带来很大危害。文章对长凼子隧道岩溶突水、突泥特征及控制因素进行了分析,其分析结果对类似岩溶隧道的勘察、设计、施工,以及综合超前地质预报具有重要的指导作用和参考价值。
Changdangzi tunnel traverses Qiyaoshan anticlinorium of Daxihe watershed,while Daxihe being the branch of Yangtse River.Karsts and karst water in the tunnel region are affected by physical geography,topography,physiographic stage,lithology and structural geology that karsts are developing and groundwater is abundant.The tunnel is situated in a complex carbonate karst region.In this paper,the control factors of karst water motion in the tunnel are analyzed in detail and the results have important reference value for the surveying,design and synthetic geology prediction for similar karst tunnels.
