高度跨度世界第一 花江峡谷大桥荷载试验启动

Core Viewpoint - The load testing of the world's highest bridge, the Huajiang Grand Canyon Bridge, has officially commenced, marking a significant milestone in its construction and safety verification process [1][2]. Group 1: Project Overview - The Huajiang Grand Canyon Bridge is a key control project of the Guizhou Liuzhi-Anlong Expressway, located in Anshun City, Guizhou Province, spanning the Beipan River Huajiang section [1]. - The bridge has a total length of 2,890 meters and a main span of 1,420 meters, making it the highest bridge in the world at a height of 625 meters above the water surface [1]. Group 2: Load Testing Details - The load testing consists of three phases: empty load test, static load test, and dynamic load test, and will last for four days [1]. - A total of 15 test conditions will be arranged, with over 400 sensors deployed to monitor the deformation and stress of the bridge's main tower, main beam, and main cable under static load [1]. Group 3: Economic Impact - Once operational, the bridge will significantly reduce travel time, cutting the journey from two hours to just two minutes, and the travel time from Liuzhi Special District to Anlong County from three hours to 1.5 hours [2]. - This improvement is expected to play a crucial role in boosting economic development in Guizhou Province, facilitating resource connectivity and promoting local economic growth [2].
