文摘The pressure fluctuation amplitude is very important for the load design of structures and to research flow cavitation, using 182 sample records of fluctuation pressure obtained from model tests and prototype observations for many kinds of outlet works,this paper studies statistical characteristics of fluctuating pressure amplitude in outlet works. The results indicate that the probability of fluctuating pressure amplitude in outlet works obeys Gaussian normal distribution,and the verification of prototype observation data from Gezhouba project further proves that the conclusion is true.
