浙江省曹娥江大闸闸下冲淤调度研究初探

A preliminary study on desiltation of Cao'e River Gate in Zhejiang Province

根据曹娥江大闸的闸下泥沙特性和淤积情况,可见闸下冲淤关键是闸上冲淤水量的保证。因此,在全面分析曹娥江流域水资源的情况下,重现历史水文条件下曹娥江大闸的闸下淤积情况和曹娥江流域的来水情况,分析闸上冲淤水量的保证程度。在此基础上,对曹娥江大闸闸下冲淤调度进行初步研究。

On the basis of the sediment feature and the status of the sedimentation behind the Gate of Cao＇ e River, it is known that the desiltatior, therein depends fully on the guarantee of the water amount before the gate. Under this circumstance, the guarantee of the water amount for desihing the sidementation is analyzed based on the comprehensive analysis of the water resources of Cao＇e River Basin by means of making the recurrence of the sedimentation behind the gate and the water incoming of the basin under the historical condition. In accordance of all of these, a preliminary study on the operation of the desiltation of the gate is accordingly made herein.
