对小浪底水库首次人工塑造异重流的探讨

Discussion on the First Manual Density Current in Xiaolangdi Reservoir

为了有效控制水库泥沙淤积的数量,改善库区泥沙淤积的形态,从而延长水库的使用寿命,小浪底水库于2004年首次进行了人工扰动塑造异重流试验。结果表明:异重流冲沙前后库尾泥沙淤积形态和数量的变化明显,认为利用人工塑造异重流进行水库冲沙是可行的。

In order to control the sedimentation amount in the reservoir and improve sedimentation topography, which was also to maintain the normal operation life of the Reservoir, the first manual sediment disturbance test, as made density curren in Xiaolangdi Reservoir in the year of 2004. the primary conclusions are as follows： before and after this manual density curren, through comparing and analyzing the change of the sedimentation topography and amount in the backwater end, the desihing is feasibility by using manual density current in Xiaolangdi reservoir.
