摘　　要：小浪底水库作为黄河流域水沙调控体系的重要组成部分，通过对国内外已有的水库壅水明流排沙、异重流潜入条件的分析，探讨了小浪底水库异重流预测的现状和难点，并提出了初步解决方案。今后须加强库区水沙因子测验，利用数学模型和物理模型两种手段，研究不同库段、不同流态的水沙输移规律，从而提高计算、预测水库排沙的精度，为小浪底水库排沙预测方法提出了方向。The Xiaolangdi Reservoir has an important role of water-sediment regulation system on the Yellow River. In this paper, analysis on sediment flushing in conditions of backwater of free flow and gravity current plunging of the existing reservoir at home and abroad has been carried out,with discussing on present situation and the hot points that forecast sediment flushing in Xiaolangdi Reservoir. A preliminary solution has been given. In future, water and sediment data survey need to be strengthened in the reservoir. By means of math and physical model, the law on water and sediment transport in different sections and different flow regimes should be studied to improve calculation accuracy of forecast reservoir flushing. A new direction on forecasting sediment flushing in Xiaolangdi Reservoir has been put forward.
