黄河万家寨水库的泥沙设计与运行

Sediment design and operation of Wanjiazhai Reservoir on the Yellow River

万家寨水库具有库区比降大、库尾以上河道比降平缓的特点,控制水库泥沙淤积末端在库尾拐上断面以下尤为重要,为此,水库泥沙设计进行了两个数模的计算和四个河工模型试验,其结果基本一致。本文还简要介绍了自蓄水到2002年的水库泥沙冲淤情况。

Wanjiazhai Reservoir owns the character that the slope of reservoir area is large, while the slope of the reach upstream the reservoir tail is gentle. How to control the tail deposition downstream Guaishang section becomes a very important issue. By using numerical calculations and physical model tests, the design for sedimentation in the reservoir is investigated. In addition, the sedimentation in Wanjiazhai reservoir from its operation to year 2002 is briefly depicted in the essay.
