Fluctuant Characteristics of Stilling Basin Floor of YinPan Hydropower Station

摘要

Stilling basin floor is light structure, its structural vibration, impact, stability and so on, directly related to the flow fluctuation intensity of hydraulic jump area of the floor. Using ODYSSEY highfrequency high-capacity data acquisition system to test and study fluctuant characteristics of stilling basin floor of YinPan hydropower station, get the hydraulic jump fluctuating load, fluctuating frequency distribution along the way, as well as the probability distribution law of fluctuating amplitude, and quantitatively analyses the worst dynamic load of stilling basin floor. The results could be reference for similar projects.
