Home Yunnan-Guangxi High Speed Railway
This “sky railway” is representative of China’s high-speed railway in mountainous areas with complicated geological hazards. It required an all-weather, high-efficiency and high quality field survey in difficult and dangerous mountain areas and implemented a “quickly identify risks, avoid major risks, prevent and control general risks, and monitor potential risks” disaster reduction approach.
The developed swelling soil subgrade deformation control technology is internationally advanced. The Nanpanjiang Super Large Bridge with a main span of 416m is the world’s largest span concrete arch bridge for mixed passenger and freight railway.
The project stretched boundaries with comprehensive treatment of tunnel karst and control of large extrusion deformation, and 12 long and high-risk tunnels above 10km.
Kunming South Railway Station is also the largest comprehensive transportation terminal in Southwest China.
