摘要
仰头山隧道是重庆市黔江—湖北省恩施高速公路重难点和控制性工程之一,需穿越二叠系、三叠系岩溶发育区,水文地质条件复杂。从岩溶发育特征、含水岩组富水性、地下水系统特征、地下水结构特征等论述隧道岩溶水文地质特征,采用降雨入渗法、径流模数法、古德曼公式法、裘布依公式法等多种方法进行隧道涌水量预测,并结合岩溶管道发育分布特征,讨论可能发生突水突泥的区段,为隧道涌突水防治及环境保护提供依据。
The paper discusses hydrogeology characteristics from the following aspects：karst development characteristics, water abundance of aquifer, system characteristics of groundwater and structural characteristics of groundwater. The au- thors make use of rainfall infiltration method, runoff modulus method, Goodman formula method and J. Dupuit formula method to forecast water inflow of tunnel. Combined with distribution characteristics of karst conduit development, the au- thors discuss these segment may occur inrush of clay and water, provide the basis for prevention of water fathering and en- vironmental protection.
