水洞沟水库泥沙淤积分析及运行方案研究

Analysis of the Sediment Deposition and Running Schemes of Shuidonggou Reservoir

根据金水源一泵站附近河段的多年监测资料,选择1996年作为典型年,分析了典型年的泥沙含量情况及泵站的运行情况,结果表明该泵站能够满足水洞沟水库正常运行。参照鸭子荡水库运行情况及相关参数,在考虑多种因素的情况下,分别对水洞沟水库三个时期的运行情况进行了分析,针对各时期提出了可行的运行方案,并计算了各方案下的泥沙淤积量。

According to the field measured data of the Yellow River near the first pumping station at Jinshuiyuan in Ningxia, 1996 was chosen as a typical year, and the sediment deposition and running schemes are discussed. The research results show that the pumping station can meet the running requirement of Shuidonggou Reservoir. Based on the given conditions and related parameters of the Yazidang Reservoir, variety of factors were considered and the running schemes of three periods of the reservoir is analyzed. In summary, the amount of sediment deposited in the reservoir of each period was calculated and feasible running schemes of the reservoir were suggested.
