Abstract: There is 75.5*108 m3 debris storage capacity obligated in Xiaolangdi reservoir. In order to use it reasonably, improve its profit usage, prolong its usage age, it is operated in various dispatching modes such as regulating and controlling water level, sand discharging in terms of density flow, lower level at the suitable time, dispatching water and sand, the coarse sand in and fine sand out. That made sedimentation in order and regulated the debris storage locations in the reservoir, which has achieved excellent effects in earlier operation.

摘要： 小浪底水库预留75.5亿m3的淤积库容，为合理利用淤积库容，提高淤积库容的利用率，尽量延长兴利库容的使用寿命，在调度方式上采用了“调控水位、异重流排沙、相机降低水位排沙、调水调沙、拦粗排细”等综合调度运行方式，使水库做到了有序淤积，调整了水库淤积部位，在初期运行管理中取得了较好的效果。
