| 摘 要： | 通过丹江口水库36年实测资料的分析研究认为:变动回水区的泥沙冲淤具有两冲一淤的周期性特点,冲淤分布受坝前两个运用水位所控制;年内具有汛、枯期两大造床期,有两个对应造床期的纵剖面;变动回水区的淤积自上至下逐段发展.由于淤积,汉库回水区有效库容损失较大.

| Abstract: | On the basis of the probe into 36 year's measurement data of Danjiangkou reservoir, the conclusion is that the silt scouring has a periodic characteristic of "Two Scour One Silt" in varying backflow zone, the arrangement of scouring is controlled by two operating water levels in front of the dam, and there are two river- bed making periods of flood and drought, correspondingly, there are two vertical sections; the silting in varying backflow develops from up section to down section. And the valid dam capacity lost a lot due to the silting. |
