Core Points - The Guizhou Huajiang Gorge Bridge has officially opened, setting world records with a vertical height of 625 meters and a main span of 1420 meters, marking it as the highest and longest suspension bridge globally [1] - The bridge features an innovative "smart nerve" system that integrates fiber optic sensors into the main cable, allowing for real-time monitoring of its health status [2][3] Group 1 - The main cable is a critical load-bearing component of suspension bridges, and its corrosion and stress changes are key indicators for maintenance [2] - Traditional maintenance methods relied on manual inspections and measurements, while the Huajiang Gorge Bridge employs a "smart cable" system for proactive monitoring [2] - The fiber optic technology used in the bridge allows for continuous data transmission regarding temperature, humidity, and stress, akin to a "heartbeat monitor" for the main cable [2][3] Group 2 - The successful implementation of fiber optics for stress testing in the main cable is a world-first, providing a basis for future research and maintenance [3] - The bridge's monitoring system can automatically alert and initiate dehumidification when parameters exceed safe limits, enhancing the safety and longevity of the structure [2]
