Vibration model test and seismic performance evaluation of polypropylene fiber reinforced concrete lining of mountainside tunnels in Loess Plateau
Currently, tunnels are key infrastructure projects for traversing the Loess Plateau and ensuring rail connectivity. However, seismic damage surveys indicate that tunnels built along mountainsides in the Loess region suffer severe damage during earthquakes due to their low structural damping and inadequate seismic per...
