一、概况 龚咀电站位于大渡河中下游的峡谷河段上,距河口90公里。主要任务是发电,兼有木材过坝、下游通航等综合效益。 坝址区河谷较窄,枯水期水面宽100～120米。河床复盖层厚10～15米,混凝土重力坝建于古老的花岗岩基础上,最大坝高85.5米(后期拟加高到150米)。壅高水位50米,库区回水长38公里,总库容3.1亿米~3,水库面积13.8平力公里。电站引用流量1687米~3/秒,装机七台,总容量70万千瓦。 龚咀坝址控制流域面积76,400公里~2,占全流域面积的98％。多年平均流量1530米~3/秒,平均年迳流量482亿米~3。实测最大流量10,400米~3/秒,实测最小流量370米~3/
I. Overview Gongzui Power Station is located in the mid-lower reaches of the Dadu River Canyon, 90 km away from the mouth. The main task is power generation, both wood dam, downstream navigation and other comprehensive benefits. The valley of the dam area is narrower, and the surface water in the dry season is 100 to 120 meters wide. Bed cover thickness of 10 to 15 meters, the concrete gravity dam built on the basis of the ancient granite, the maximum dam height 85.5 meters (later proposed to be raised to 150 meters).壅 high water level of 50 meters, 38 kilometers back to the reservoir area, the total storage capacity of 310 million meters 3, 13.8 square kilometers reservoir area. Power station quoted flow of 1687 m ~ 3 / s, installed seven, the total capacity of 700,000 kilowatts. Gongju dam site control basin area of 76,400 km ~ 2, accounting for 98% of the basin area. The average annual flow of 1530 m ~ 3 / sec, the average annual discharge of 48.2 billion m ~ 3. Measured the maximum flow of 10,400 m ~ 3 / s, the measured minimum flow of 370 m ~ 3 /
