【摘要】 回龙山大坝挑流鼻坎因体型的原因，导致泄流时产生严重的空蚀破坏。通过模型试验，分析了鼻坎１９９５ 年泄流的水力学条件，进而搞清空蚀破坏的原因。以超空化理论为基点，对鼻坎的体型进行了优化研究。更多还原

【Abstract】 Because of the body type, the serious cavitation was resulted on the bucket in Huilongshan dam during discharging. Through the model test, the bucket hydraulics property during discharging in 1995 was made analysis, and the reason of cavitation was found out. According to the supercavitating theory, the bucket type was made optimization. [更多还原
