摘　　要：水工隧洞设计时,通常将水流势能作为计算依据,常常忽略了水流动能在闸门关闭时形成的水击压力对隧洞结构配筋的影响。以某水库正常蓄水位工况下泄洪为例,计算不同闸门关闭时间产生的水击压力,从而分析得出水击压力对泄洪输水隧洞配筋影响。In the design of hydraulic tunnel,flow potential energy is usually taken as the calculation basis,and the influence of water hammer pressure formed by water flow energy on reinforcement of tunnel structure when gate is closed is often neglected.Taking flood discharge of a reservoir under normal water level as an example,the water hammer pressure generated by different off times of gates is calculated,and the influence of water hammer pressure on reinforcement of flood discharge and water conveyance tunnel is analyzed.

关 键 词：泄洪输水隧洞 水击压力 结构配筋 关闭时间
