摘要 本文对水库洪水波传播的波速进行了研究。结果表明:运动波波速代表洪峰处的传播速度,而惯性波波速则代表波锋处的传播速度;天然河道或水库河流区观测的洪峰波速是运动波波速,而在水库平水区通过闸门启闭观测到的波速则是惯性波波锋处的传播速度。 An investigation is made into the celerity of reservoir flood wave propagation.It is shown that the celerity of the kinematic wave represents the propagation speed at flood peak and the celerity of inertia wave represents the propagation speed at the wave front. The wave speed at the flood peak observed in a natural river or the river reach of a reservoir is the celerity of the kinematic wave, but the wave speed due to gate operation observed at the horizontal stage reach of a reservoir is the propagation speed at the front of the inertia wave.
