“横竖”都是第一，底气何来（创新谈）

Core Viewpoint - The construction of the Huajiang Gorge Bridge exemplifies China's advancements in engineering technology through independent innovation and the strengthening of the "engineer dividend," showcasing the country's exceptional organizational and collaborative capabilities in complex mega-system engineering [1][4]. Group 1: Engineering Technology Breakthroughs - The Huajiang Gorge Bridge, with a total length of 2890 meters and a main span of 1420 meters, is the world's highest bridge at a vertical height of 625 meters above the water surface, marking a significant achievement in engineering technology [1][2]. - The project utilized 2000 MPa high-strength steel wires, capable of lifting 10 small cars, and incorporated advanced technologies such as a Doppler laser radar wind measurement system and a "smart cable" system, demonstrating a shift from following foreign practices to developing proprietary technologies and standards [2][3]. Group 2: Project Management and Innovation - The construction team integrated multiple cutting-edge technologies to create a "cloud construction" system, completing 21,000 tons of steel beam alignment in just 73 days and paving 38,000 square meters of bridge surface in over a month, significantly reducing the construction cycle [3]. - The project adopted a "ranking system" to form specialized teams, gathering technical expertise and promoting the deep integration of innovative results with engineering practice, reflecting China's strong organizational and collaborative capabilities in complex engineering projects [3]. Group 3: Role of Engineers and Future Directions - Engineers are recognized as a vital force in advancing engineering technology and are essential to national strategic talent, with the Huajiang Gorge Bridge project team overcoming numerous world-class challenges and receiving the "National Excellent Engineer Team" honor [4]. - China is positioned at the forefront of engineering technology, particularly in major infrastructure construction, but still has room for improvement in key materials, core components, and supporting software, emphasizing the need for enhanced independent innovation capabilities to meet national strategic demands [4].
