3D打印般精密“生长”，世界第一高坝如何智能建造？

Core Viewpoint - The Xinjiang Dashi Gorge Water Conservancy Hub Project has officially transitioned from construction to operational preparation, marking a significant milestone in China's major water conservancy projects [1] Group 1: Project Overview - The Dashi Gorge Water Conservancy Hub features a maximum dam height of 247 meters, equivalent to over 80 stories, setting a world record for the construction of concrete-faced rockfill dams [1] - The project is located in the seismically active Tianshan Wensu Grand Canyon, presenting complex geological conditions [1] - The hub employs "smart construction" techniques to address challenges such as high seismic intensity and rapid flood discharge [1] Group 2: Construction Techniques - The dam incorporates over 9,000 high-strength anti-seismic steel bars and uses civil geogrids laid in layers every 10 meters to create a stable structure from loose gravel [3] - The construction process utilizes a "layered paving and layered compaction" technique, with autonomous vibrating rollers and smart construction machines working in coordination to ensure the dam's stability and seismic resistance [3] Group 3: Innovative Monitoring and Management - The "additional quality method" serves as a "cardiac monitor" for the dam, using vibration wave data to monitor internal density, replacing 60% of traditional manual inspections and improving detection efficiency by over 50% [5] - Blockchain technology has been introduced for concrete data collection and smart transport management, creating a "concrete ID" system that ensures traceability and quality control from raw materials to pouring [7] Group 4: Digital Twin and Smart Management - The digital twin smart center integrates cloud computing, artificial intelligence, virtual simulation, and blockchain, ensuring real-time data transmission from various construction sites through 360-degree cameras and thousands of sensors [9] - This "smart brain" will enable dynamic flood control and health monitoring of the dam using real-time meteorological and hydrological data [11] Group 5: Environmental Protection Initiatives - The project includes a fish breeding and release station to mitigate the ecological impact of the dam, with facilities for breeding, artificial spawning, and releasing fish [13] - A total of 92,000 fish fry have been released into the Kumalake River to replenish native fish populations affected by the construction [15] - An investment of 65 million yuan has been allocated for various protective measures, including ecological fishways and fish breeding stations, resulting in the release of 141,000 fish to date [17]
