一、工程及地质概况本工程为河床式电站,设计水头18米,最大坝高40米,装机容量18万千瓦,完成的主要工程量有土石方170.27万立方米,混凝土37.21万立方米,灌浆26,315米。电站于1969年底开工,基建工程于1975年基本完成,同年6月第一台机组发电,1980年全部安装运转。由于勘测及选坝工作粗糙,在一期基坑开挖后曾发现两条顺河大断层F_(23)、F_(24)横穿坝
I. Engineering and Geological Survey The project is a river bed type power station with a designed head of 18 meters and a maximum dam height of 40 meters with an installed capacity of 180,000 kilowatts. The completed major works include 1,772,700 cubic meters of earth and stone, 372,100 cubic meters of concrete, grouting 26,315 Meter. The power station started construction at the end of 1969, and the infrastructure construction was basically completed in 1975. In the same year, the first generating unit was started in June of that year and all of them were installed and operated in 1980. Due to the rough survey and dam selection, two large faults F_ (23) and F_ (24) across the dam have been found after excavation of a foundation pit.
