摘　　要：通过对小浪底水库异重流各种水文要素进行观测,掌握库区水位和进出库水沙量的变化过程,进而确定塑造小浪底水库异重流的水库运用水位。结合历年异重流测验的经验和小浪底库区的地形条件,认为利用异重流输沙和排沙特性,可以达到排沙减淤或者改变库区淤积形态的目的。Through the observation of the Xiaolangdi Dam reservoir density currents of various hydrological factors,grasp the reservoir water level and the import library for water and sediment change process,and then determine the reservoir form the Xiaolangdi Dam reservoir density currents using water density current test,combining historical experience and the Xiaolangdi Dam reservoir terrain conditions,that the use of density flow sediment transport and sediment characteristics,can achieve the sediment ejection or the purpose of shape change the reservoir sedimentation.
