一、工程概况与研究目的东江水电站位于湖南省资兴县东江镇上游11km的耒水方石峡谷。本工程以发电为主,兼有防洪、航运及工业用水等效益,电站装机容量为50万kW,该枢纽工程主要由拦河大坝、滑雪式溢洪道、两岸放空洞和坝后厂房组成。拦河大坝为混凝土双曲拱坝,坝顶高程249m,最大坝高157m.水库特征水位列于表1中。相应于正常高水位的库容为81.2亿m~3。
First, the project overview and research purposes Dongjiang Hydropower Station is located in Zixing County, Hunan Province, Dongjiang upstream 11km Xuan Shui Fangshi Gorge. The project is mainly power generation with the benefit of flood control, shipping and industrial water supply. The installed capacity of the power station is 500,000 kW. The project is mainly composed of dam dams, ski spillways, emptying tunnels and damhouses on both sides of the dam. The dam is a concrete double curvature arch dam, with a crest elevation of 249m and a maximum dam height of 157m. The reservoir characteristic water level is shown in Table 1. Corresponding to the normal high water level of storage capacity of 8.12 billion m ~ 3.
