摘要

The discharge capacity, pressure and downstream dissipation for scour prevention under fluctuating pressure of the power station headwork spillway dam were measured and analyzed through model test. The research showed that the discharge capacity of the spillway dam met the design requirement, the designed body type of the spillway dam met the requirement of standards. The modified spillway basin body type and the downstream protection type could meet the requirement of dissipation for scour prevention. In the experiment, the mean square root, spectral characteristics and amplitude sampling of the spillway dam flow fluctuating pressure were measured and analyzed. The maximum fluctuating pressure mean root was about 4.31m water column, the dominant frequencies of flow fluctuating pressure at all measuring points ranged from 0.01 to 2Hz (prototype), and the random process of the flow fluctuating pressure conformed to probability normal distribution (Gaussian distribution) on the whole.
