| 摘 要： | 本文阐述了在低坝中应用消力戽宣泄单宽流量１～５．５ｍ３／ｓ·ｍ时的下游水流流态演变规律及各种流态下的冲刷特性，并探讨了小流量初始泄流对下游河床的影响。得出的结论是：在适宜的水力要素及结构尺寸条件下，随着消力戽下游水位由低向高变化，依次出现与高坝中相同的水流流态。在溢流低坝中采用消力戽消能在技术上是可行的。

| Abstract: | The flow characteristics of bucket basin and scouring characteristics in small dam are discussed,and the impact of initial low spillway discharge on the downstream bed is studied.Upon condition that both hydraulic element and structure size are suitable,hydraulic similarity between small dam and high dam existe when the water level in bucket basin increase.Using bucket basin in small spillway is technologic feasible. |
