摘要
待建的红石岩水电站水库属严重淤沙型水库,通过动床水工模型试验和有关研究分析发现,其冲沙闸排沙效果不理想,引水隧洞存在进沙严重的隐患。为此,提出了增设一道导墙的方案,以减少引水隧洞进沙并提高冲沙闸排沙效果。同时,从提高电站的经济效益考虑,对运行方式提出了建议。
Based on the moveable-bed model tests and some relative studies, it is found that the proposal reservoir for the Hongshiyan Hydropower Station will be a heavy deposit reservoir, its sand-flushing sluice could not effectively de-silt and serious hidden-troubles exist in its diversion tunnel. For this reason, this paper puts forward a guide wall should be increased to reduce the sand flowing into the tunnel and increase sand-flushing effectiveness of sand gate. In addition, several operation suggestions have also been advised to enhance economic benefits of the hydropower station.
