摘　　要：弧形闸门属轻型结构,其振动、稳定性等直接与水流脉动压力相关。为研究弧形闸门上水流脉动压力特性,在试验室内开展了一系列模型试验,通过对闸门面板上大量测点水流脉动压力数据的系统分析,获得了水流脉动压力幅值和频率在闸门面板上的分布规律,以及闸门开度、上下游水位变化对脉动压力的影响。Radial gate is a kind of light structure and its structural vibration and stability have direct relationship with fluctuating water pressure. A series of experiments have been conducted to investigate the characteristics of fluctuating pressure on radial gate. Through comprehensive analysis on measured data of fluctuating flow pressure from a great many measure points on the plate of gate, the distribution laws of dynamic flow pressure amplitude and frequency, and the effects of gate opening and upstream and downstream water level variations on fluctuating pressure are acquired.
