Abstract: According to discharge modes of Shiquan reservoir, cavitation of high-speed flow on bucket dissipater of middle and surface outlet were studied. As well, influence of discharge and flood on bucket dissipater after the recent overhaul was researched. This paper summarized the operation points for attention and damage law of bucket dissipater of Shiquan reservoir, worthy reference in future operation.

Key words: bucket dissipater, Shiquan reservoir, cavitation, influence

摘要： 根据石泉水库泄流方式，分析高速水流对石泉中孔消力戽和表孔消力戽空蚀影响，统计最近一次消力戽大修后泄流对消力戽的影响，并在洪水过后及时抽水检查，进行验证，将石泉消力戽的运行注意事项和损坏规律总结出来，指导今后的运行。
