记者手记：一座长江大桥的拔节“生长”

Core Viewpoint - The Zhang Jinggao Yangtze River Bridge is a significant infrastructure project aimed at enhancing connectivity in the Yangtze River Delta region, showcasing advanced engineering and innovative technologies [1][5]. Group 1: Project Overview - The bridge, approximately 29.85 kilometers long, is a key project during China's 14th Five-Year Plan, expected to be completed by the end of 2028 [1]. - The construction of the bridge began with a groundbreaking ceremony on June 28, 2022, and the main engineering work commenced in October of the same year [1]. Group 2: Engineering Innovations - The bridge features six world records, including the longest span for a suspension bridge at 2,300 meters and the highest suspension bridge tower [2]. - Innovative technologies include a self-balancing cable force system, ultra-high-strength main cables, and a digital bridge concept that integrates smart monitoring and maintenance systems [2][4]. Group 3: Environmental Impact - The application of the self-balancing cable force technology is projected to save 15,700 cubic meters of concrete and 12,560 tons of steel, reducing carbon emissions by over 80,000 tons [2]. Group 4: Operational Safety - The bridge will utilize sensors to collect real-time data on environmental conditions and structural responses, aiding in scientific decision-making for its operation and maintenance [3]. Group 5: Strategic Importance - The bridge is a crucial initiative for the integrated development of the Yangtze River Delta and the Yangtze Economic Belt, aiming to become a model for transportation infrastructure and bridge technology innovation in China [5].
