摘　　要：通过研究消力戽消能工的工作原理,阐述了戽流消能时的流态为高序列流态淹没混合流及淹没面流,介绍了回复底流的产生机理和危害。通过工程实例,说明适当地增大戽坎反弧半径可以有效避免发生回复底流,并检验了判别是否发生回复底流关系式的准确性。This paper studies the working principle of the bucket basin energy dissipater, expounded the flow state is the high - flow state sequence of submerged admixture flow and submerged surface flow when bucket flow dissipated energy, introduced the generation mechanism and hazards of the reply underflow. Through engineering example to illustrate increased bucket＇ s radius moderately can a- void underflow reply effectively, and tested the relationship of determine whether the reply underflow occurs ＇ accuracy.

关 键 词：消力戽 混合流 回复底流 反弧半径
