三座店水库泥沙淤积计算分析

三座店水库位于高含沙的阴河，水库面临着严重的泥沙淤积问题。水资源供给和水库淤积存在着尖锐的矛盾。利用一维不平衡输沙数学模型，对水库的淤积进行了计算分析。综合考虑了水库设计中的主要因素，如水库运行方式、大坝规模、坝址、泄流设施等因素。并探讨研究了降低水库运行水位以及利用异重流排沙等措施减小水库淤积的可行性，对水库运行50a后的泥沙淤积情况进行了预测。

Sediment computation and analysis of Sanzuodian reservoir

The Sanzuodian reservoir is located on the Yinhe river with high sediment content and the reservoir faces severe sediment deposition problem. Violent contradiction is developing between water supply and reservoir sediment deposition. In this paper, a one-dimension unbalanced sediment transportation mathematical model is used to compute the sedimentation deposition in the reservoir. The main factors in reservoir design are considered, such as the reservoir operation mode, the dam scale, the dam site, flood discharge facilities etc. The feasibility of reducing the reservoir sedimentation by lowering the reservoir operation level and using density flow to flush sediment is studied and the sedimentation condition after 50 years of the reservoir operation is forecasted.
