1991年9月19～28日,水利水电规划设计总院会同四川省建委、计经委在成都召开了南垭河冶勒水电站初步设计报告审查会、国家能源投资公司与省、地、县、高等院校、科研设计等26个单位的代表和专家共161人出席了会议。与会代表听取了成都勘测设计院关于冶勒水电站初步设计介绍,查勘了现场,并分组进行了讨论和审查.冶勒水电站是南垭河梯级开发中最上游一级,采用混合式开发。坝址位于冕宁县冶勒乡,距石棉县城54Km。厂址位于石棉县南垭村。枢纽位于高寒山区,冬季长达半年,雨季多达215d,自然条件恶劣。坝址区河床及右岸覆盖层深厚,最大厚度大于420m,其工程地质与水文地质条件极为复杂,为国内外罕见。自1972年以来,成勘院在条件十分艰苦的情况
From September 19 to September 1991, the General Planning and Design Institute of Water Conservancy and Hydropower, along with the Sichuan Provincial Construction Commission and the Commission for Economic Planning and Development held a review meeting on the preliminary design of the Nanya River Yele Hydropower Station in Chengdu. The National Energy Investment Company and the provincial, prefectural, A total of 161 delegates and experts from 26 institutions including universities and research institutes attended the conference. Participants listened to the survey and design institute of Chengdu about the preliminary design of Yele Hydropower Station, surveyed the site, and discussed and examined in groups. Yele Hydropower Station is the most upstream level of the Nanya River cascade development and adopts hybrid development. Dam site is located in Mianning County Yele Township, 54km away from Shimian county. The site is located in Shimian County, South Ya Village. Located in the alpine mountainous area, winter up to six months, up to 215 days during the rainy season, poor natural conditions. The riverbed and the right bank cover in the dam area are deep and the maximum thickness is more than 420m. The engineering geology and hydrogeology conditions are extremely complicated and rare at home and abroad. Since 1972, the Institute has been in very difficult conditions
