据美国《工程新闻记录》1978年4月6报道,美国哥伦比亚河上的大约瑟夫电站,位于大古里坝的下游,于五十年代初期建成。当时根据电力需要,在27台机组中只安装了16台,容量共102.4万千瓦。因电力需要增长,现继续安装11台新的机组。大古里坝第三厂房建成后,从尾水管下泄的流量增加,为了容纳这一部分水量,需增加大约瑟夫水库的库容,抬高水库的正常高水位。为此目的,需将大坝加高10英尺。由于水头和流量的增加,大
According to the U.S. “Engineering News Record” reported on April 6, 1978, the large Josephson power station on the Columbia River in the United States, located downstream of the Bigouli Dam, was completed in the early 1950s. At that time, according to the power needs, only 27 units were installed in 27 units with a total capacity of 1,024,000 kilowatts. Due to the increased power demand, 11 new units are now installed. After the completion of the third large-scale dam at Grand Canyon Project, the flow discharged from the tail pipe will increase. To accommodate this part of the water volume, the reservoir capacity of the Joseph Reservoir needs to be increased to raise the normal high water level of the reservoir. For this purpose, the dam needs to be raised 10 feet. Due to the increase of head and flow, large
