华电金上拉哇水电站大坝填筑到顶

Core Insights - The completion of the last layer of the dam at the Huadian Jinshanglawa Hydropower Station marks a significant milestone in the construction of the world's highest panel rockfill dam power station, laying a solid foundation for subsequent water storage [1][3]. Group 1: Project Overview - The Lawa Hydropower Station is located at the confluence of Sichuan Province and the Tibet Autonomous Region on the mainstream of the Jinsha River, and is a key component of the national "14th Five-Year Plan" for clean energy development [3]. - The total installed capacity of the project is 2 million kilowatts, with a reservoir capacity of 24.67 billion cubic meters and a maximum dam height of 242.5 meters [3]. - Since the start of dam filling in June 2023, approximately 16.2 million cubic meters of material have been filled [3]. Group 2: Construction Technology and Achievements - The dam is situated in a high seismic intensity zone with complex geological conditions and significant temperature variations, which necessitated the use of intelligent construction technology [3]. - The innovative "Lawa Cloud" intelligent construction system was developed to achieve intelligent perception, real-time analysis, and feedback control throughout the dam construction process [3]. - The project has successfully implemented a large-scale, fully automated roller compaction system, filling a gap in intelligent construction technology for large panel rockfill dams under complex geological conditions [3]. - The maximum settlement rate of the dam is only 0.54%, significantly better than the design specifications, and the project has received several awards, including the National Science and Technology Progress Award (second class) [3]. Group 3: Current Status - The first phase of concrete pouring for the dam has been completed, and the electromechanical installation work is progressing in an orderly manner [5].
