大国工程激发经济新动能 “世界第一高坝”彰显科技创新的中国力量

Core Viewpoint - The construction of the Shuangjiangkou Hydropower Station, a key energy project under China's 14th Five-Year Plan, is progressing rapidly, showcasing the country's commitment to enhancing its energy capacity and infrastructure [3][6]. Group 1: Project Overview - The Shuangjiangkou Hydropower Station has an installed capacity of 2 million kilowatts and an average annual power generation of 7.7 billion kilowatt-hours [3]. - The dam, designed to be the highest in the world at 315 meters, has a total fill volume exceeding 46 million cubic meters, which could form a wall that wraps around the Earth's equator if constructed as a one-meter square wall [10][12]. Group 2: Recent Developments - On May 1, 2023, the reservoir of the Shuangjiangkou Hydropower Station completed its first water storage, marking a significant step towards operational readiness [6][8]. - The current water storage level has reached 1.1 million cubic meters, equivalent to nearly 8 West Lakes, with plans to raise the water level by over 150 meters by 2027 [8]. Group 3: Engineering Challenges - The dam's construction has reached a height of 205 meters, with an additional 110 meters planned, presenting substantial engineering challenges due to the rapid rise in water levels [10][12]. - The dam's design features a trapezoidal structure, with a base thickness of 1,400 meters tapering to 16 meters at the top, enhancing its stability against the pressure from upstream water [10]. Group 4: Future Impact - Once operational, the Shuangjiangkou Hydropower Station is expected to generate over 7 billion kilowatt-hours annually, supporting downstream hydropower stations to increase their output by 6.6 billion kilowatt-hours, sufficient to meet the annual electricity needs of 3.26 million households [12].
