摘要
水库建成蓄水后 ,因地下水位抬高 ,对地下水工隧洞将作用较大的外水压力。文章针对乌江洪家渡水电站左岸泄洪系统地下洞室的外水压力分析 ,结合部分已建工程的实际经验 ,在大量结构计算的基础上 。
After reservoir impounding, underground hydraulic tunnels will by acted by large pressure of water outside because of underground water level rising. Analyzing on pressure of water outside underground tunnels of spillway system on the left bank of Hongjiadu Hydropower Station, design thought and treatment measure of pressure water outside are presented in this paper on base of largely structure calculating.
