(一)简况石门水利枢纽为褒河第一期开发工程,是以灌溉为主结合发电的综合利用大(二)型工程。该工程于1969年动工兴建,1973年建成。枢纽工程由双曲混凝土拱坝、河床电站、河东、河西电站和反调节池组成。坝高88米,坝顶高程620米,水库设计正常水位为618米,相应库容1.05亿米~3,有效库容0.607亿米~3,是一座季调节水库。设计灌溉面积51.5万亩,灌溉保证率为67.7％。修建有东、西、南三条干渠,总引水流量56米~3/秒。河床、河东、河西三处水电站安装有六台水轮发电机组,总装机容量4.05万千瓦,年发电量1.407亿度。
(I) Brief introduction Shimen Water Control Project is the first phase of Baohe River development project, which is a large-scale comprehensive utilization project with irrigation mainly combined with power generation. The project started construction in 1969, completed in 1973. The hub project consists of hyperbolic concrete arch dam, river bed power station, Hedong River, Hexi power station and anti-regulation pool. Dam height of 88 meters, the crest elevation of 620 meters, the reservoir design of the normal water level of 618 meters, the corresponding storage capacity of 105 million meters ~ 3, the effective storage capacity of 607 million meters ~ 3, is a seasonally adjusted reservoir. Design irrigation area of 515000 mu, irrigation guarantee rate of 67.7%. Built east, west and south three main channels, the total water diversion flow of 56 m ~ 3 / sec. Riverbed, Hedong, Hexi three hydropower stations installed six hydroelectric generating sets, with a total installed capacity of 40,500 kilowatts, the annual generating capacity of 140.7 million degrees.
