某水电站地下厂房渗控分析研究

Analysis and Research on Seepage Control of Underground Powerhouse of a Certain Hydropower Station

某水电站工程规模大,输水线路长度相对短,地下厂房距离坝轴线约210 m,蓄水后渗流特性或将成为影响正常运行的重要因素。通过建立渗控系统的三维有限元模型,开展工程区域在各种工况下的三维渗流分析。计算结果表明:防渗排水系统方案布置合理、有效,可满足地下厂房系统运行要求。

The scale of a certain hydropower station project is large,and the length of the water transmission line is relatively short.The underground powerhouse is about 210 m away from the dam axis.The seepage characteristics after water storage may become an important factor affecting normal operation.By establishing a three-dimensional finite element model of the seepage control system,conduct three-dimensional seepage analysis of the engineering area under various working conditions.The calculation results indicate that the layout of the anti-seepage and drainage system scheme is reasonable and effective,and can meet the operational requirements of the underground power plant system.
