为了满足成都地区日益增长的工业用电要求,早在1954年5月就由原西南水电勘测处进行岷江上游的勘测工作,并编制综合利用规划报告,继由成都水电设计院于1956年4月将该规划编制完成。重点研究了岷江茂县到灌县一段河流,计划分八级开发,并选定岷江上游紫坪舖水电站为第一期工程。它的装机容量约为狮子滩水电站的6—7倍,为我国目前大水电站之一。初步设计的勘测设计工作于1956年复秋两季分别开始,1956年第四季度起已开始施工准备工作,1957年正式开工。兹将紫坪舖水电站的自然概况及坝址选定情况分述于后。
In order to meet the growing demand for industrial electricity in Chengdu, as early as May 1954, the former Southwest Hydropower Survey Department conducted surveys on the upper reaches of the Minjiang River and prepared comprehensive utilization planning reports. Following on from the Chengdu Hydropower Design Institute in April 1956 The plan is completed. The study focused on a section of river from Mao County to Guan County in Minjiang County. It is planned to develop in eight levels and select the Zipingpu Hydropower Station in the upper reaches of the Minjiang River as the first phase of the project. Its installed capacity is about 6-7 times that of Shizitan Hydropower Station, which is one of the largest hydropower stations in our country at present. Preliminary design of the survey and design work in the autumn and autumn of 1956, respectively, began in the second quarter of 1956, began construction preparations, officially started in 1957. The Zipingpu Hydropower Station natural conditions and dam site selection will be described later.
