| 摘 要： | 刘家峡水电站尾水河床，在电站施工期及运行初期因各种因素影响，造成河床内堆渣、冲坑交替发生，局部河段河底高程已抬高了10m，水下地形已稳定。若采取措施，在局部河段清渣，尾水位高程降低，发电量增加，经济效益十分可观。

| Abstract: | Due to various origins during construction and operation debris deposition and scouring pit occur alternatively in the tailrace channel of the Liujiaxia hydropower station. The local riverbed has raised by 10 m and the bottom profile is stabilized. If measures are adopted to remove the debris deposited in the riverbed and reduce the tailwater level, the economic benefit is considerable by increasing power generation. |
