大渡河金川水电站进入投产倒计时
Zhong Guo Jing Ji Wang· 2025-10-21 07:47
10月21日,大渡河上游重点工程——国家能源集团金川水电站下闸蓄水,标志着金川水电站正式迈入投 产倒计时。项目采用坝式开发,以发电为主,总装机容量860兆瓦,是四川省"十四五"能源发展规划重 点建设项目。 金川水电站位于四川省阿坝藏族羌族自治州金川县、马尔康市境内,是大渡河干流水电规划28级方案中 的第6个梯级电站,于2018年12月核准开工。该水电站属国内河流深厚覆盖层(河床堆积物)上建设的最 高面板堆石坝,施工人员要在25米级跨度极破碎岩体中建设地下厂房,施工难度极大。 金川水电站地处高山峡谷区,汇集了河床深厚覆盖层、松弛岩体、破碎岩层等工程领域地质问题。相关 工程引入BIM(建筑信息模型)三维建筑信息模型技术,辅助地质分析、施工预演、风险分析等流程,建 成了国内首个BIM水电工程全生命周期信息模型标准体系,完成了BIM技术参数国产化,实现了以重大 工程项目带动科技创新与突破。 金川电站在建设的同时,还非常注重保护生态,这里建设有亚洲最长的仿生态鱼道,通过天然河道加隧 洞的方式,为大渡河特有的洄游鱼类提供生态保障,用实际行动守护青山绿水、蓝天白云。 "金川电站建成后,年均发电量约35亿千瓦时,每年可替代约 ...

Core Viewpoint - The successful impoundment of the Dadu River Jinchuan Hydropower Station marks a significant step towards its commissioning, with the potential to replace approximately one million tons of coal consumption annually, contributing to a reduction in carbon emissions and optimization of China's energy structure [1][5]. Group 1: Project Overview - The Jinchuan Hydropower Station, located in Aba Prefecture, Sichuan Province, is the sixth hydropower station in the Dadu River's 28-level planning scheme, with a total installed capacity of 860 megawatts [1]. - The construction faced significant challenges due to complex geological conditions, being the highest rockfill dam in a deep cover area in China, with a construction difficulty level considered the highest domestically [1]. Group 2: Environmental and Technological Innovations - The project includes Asia's longest ecological fishway, designed to protect migratory fish species in the Dadu River, demonstrating a commitment to ecological preservation [3]. - The Jinchuan Hydropower Station has established China's first fully domestic three-dimensional digital modeling standard system for hydropower projects, enhancing geological analysis, construction simulation, and safety management [3]. Group 3: Economic and Environmental Impact - Upon completion, the Jinchuan Hydropower Station is expected to generate an average annual electricity output of approximately 3.5 billion kilowatt-hours, significantly contributing to reducing carbon emissions by about one million tons per year [5].
金川水电站成功下闸蓄水 每年可替代约百万吨燃煤消耗
