摘要
刘家峡电站近二十年来，泥沙问题给电站的安全发电和渡汛带来了极其严重危害，经对电站泥沙问题的研究与运用实践认为：从发电与解决泥沙危害综合考虑，电站采用高水位运行异重流排沙和低水位拉沙，可有效解决电站近期泥沙问题。实践证明：采用这些途径取得了显著的排沙减淤效果和经济效益，保证了电站安全运行。
The Liujiaxia hydropower station has been operated for more than 20 years.The sedimentation has seriously influenced on the electric generation and flood discharge.From the research of long time observation and experience,it is found that the sedimentation problem can be solved by two approaches in different times of operation of the station.To desilt the sediment by discharging density variation currents in flood period, while the pool water level is high; by discharging the sediment with entrainment by water current while the pool level of the reservior is low before the beginning of flood season.The practice shows that the two methods have produced obvious favorable results and economic benefits.Safe operation of the power station has thus been guaranteed.
