东江水电站位于湖南省耒水上游。坝址处河各狭窄陡峭,常水位水面宽20～40m。其枢纽布置为双曲拱坝(坝高157m)、系坝后式厂房(装机容量4×125MW)。在左岸设一孔滑雪式溢洪道(斜切挑坎)及一级泄洪兼放空洞,右岸设二孔滑雪式溢洪道(窄缝挑坎)及二级放空洞。水库正常高水位为285m。在狭谷地区修建高拱坝,枢纽及消能防冲布置是一个较为困难的问题。东江水电站在国内首次采用了
Dongjiang Hydropower Station is located in the upper reaches of Lishui in Hunan Province. The dam site at the narrow steep, often water level surface width 20 ~ 40m. Its hub layout for the double curvature arch dam (dam height 157m), Department of dam-style plant (installed capacity of 4 × 125MW). On the left bank, there is a one-hole ski spillway (chamfering pick-up ridge) and a first-stage flood discharging and drainage tunnel. On the right bank is a two-hole ski-type spillway (narrow-tipped spillway) and a secondary drainage tunnel. The normal high water level of the reservoir is 285m. In the valleys to build high arch dam, hub and energy-saving anti-punching arrangement is a more difficult issue. Dongjiang Hydropower Station was first adopted in China
