大坝泄洪采用全表孔方案，溢流坝段表孔以下采用碾压混凝土，碾压混凝土总量58.76万m3，占坝体混凝土总量的58%。

The top openings are designed for flood release and the dam body under the top openings is RCC with its volume of 587.6 thousand m ~ 3 , accounting for 58 % of total dam concrete volume .

泄洪隧洞工作水头达120m，采用双孔合一的闸门布置形式，高水头大流量的泄洪消能问题十分突出；

The maximum operation head of spillway tunnels is 120m , two orifices of water gate combine to be a hole in the spillway tunnels , the problem of discharge and energy dissipation is very complex ;

随着我国水利事业的不断发展和巨型水电站的兴建，一批200m～300m量级的高坝将相继建成，这就意味着其泄洪最大流速将达50.0m/s左右。

With the development of the hydraulic engineering , a lot of huge hydroelectric stations and high dams have been constructed , which means the maximum velocity of the flood discharge will come to 50.0m/s approximately .

通过温控研究，缩短了泄洪闸轴线长度5.5m，节约混凝土方量10000多方，折合人民币约300多万元。

Through the studies on temperature control , we shorten the total length of axis of the floodgate of releasing floodwater by 5.5 m , economize more than 10000 m3 concrete , convert more than 3 million yuan .

在WES堰或泄洪建筑物的表孔、中孔、底孔中，其下缘体型曲线将很重要，这方面前人已经做了很多工作，但在如今的高坝设计中尚还不是很如意。

Weir release floodwater form hole , middle hole , underport of building in WES , reason size curve very much important under it , in this respect forefathers make much work already , but not yet no as one wishes even of the high design of dam of today .
