Study on Impact of Reservoir Leakage on the Proposed Tunnel Project in Metamorphic Region

Abstract:

Taking into account the narrow terrain, the proposed highway has to be built near the reservoir in the study area of metamorphic rock. Furthermore, part of the tunnel elevation is lower than the reservoir of a hydropower station. If the horizontal distance between the reservoir and tunnel is far enough and the differential head is large enough, it is likely that the serious leakage of the hydropower station reservoir will occur. The interaction between highway construction and reservoir is to be the key point. Either the safety of tunnel construction and operation or the safety of reservoir storage is important. This paper use the Darcy’s law and the hydrogeological characteristics of metamorphic rock to estimate the lateral seepage and evaluate the line design.
