Strengthening

The Nanji Men Rail Bridge in China is the first of its kind in China to extensively use steel spring floating slab track beds. When trains pass through the bridge at high speed, the entire steel spring floating slab track bed can not only reduce the noise of train operation but also minimize the vibration of the bridge deck. The monitoring system conducts real-time monitoring of the bridge's vibration, main beam stress, and environmental loads during the operational period.
