2.
The chute or tunnel spillway is most often used water discharge structure in hydropower projects, along which the flow is usual not aligned with the general direction of the flow in the reservoir owing to the limit of terrain.
明流溢洪道(洞)是水利水电工程常用的溢流设施,由于布置的需要,引水渠往往存在一定程度的平面转向,这就导致水面产生不同程度的横向比降,甚至出现漩涡,如果其影响达到下游泄槽急流段,还有可能产生急流冲击波,致使水流自由水面波动,直接威胁泄水建筑物乃至大坝的安全。
