1异重流测验综述1．1水库及断面布设情况小浪底水库位于黄河中游最后一段峡谷的出口处,上距三门峡水库130km,下距花园口水文站128km,以防洪、防凌、减淤为主,兼顾供水、发电。水库坝址以上控制流域面积69．42万km~2,占黄河流域面积的92．3％,水库总库容126．5亿m~3,死库容75．5亿m~3,有效库容51．0亿m~3。1999年10月28日开始下闸蓄水。小浪底水库属于典型的河道型水库,上窄下宽,最窄处不足300m,最宽约为1000m。库区内主河道弯道较多,对异重流的纵
1 Overview of different gravity flow test 1.1 Layout of reservoirs and sections Xiaolangdi Reservoir is located at the exit of the last gorge in the middle reaches of the Yellow River, 130km away from Sanmenxia Reservoir and 128km away from Huayuankou Hydrological Station with flood control, Take into account water supply, power generation. The control basin area above the reservoir dam site is 694.2 thousand km 2, accounting for 92.3% of the total area of the Yellow River basin. The total reservoir capacity is 12.65 billion m 3, and the dead storage is 7.55 billion m 3, with an effective storage capacity of 51. 0 billion m ~ 3. October 28, 1999 began impounding impounding. Xiaolangdi Reservoir is a typical channel reservoir, narrow from top to bottom, the narrowest point less than 300m, the maximum width of about 1000m. The main river bend in the reservoir area more, longitudinal flow of different heavy
