Abstract

The objective of this research is to assess the seismic-induced dynamic reactions of tunnels in fault-fragmented areas and to explore efficient seismic countermeasures. Using the Tajikistan-China Highway Phase II as a reference, a numerical simulation is conducted to create a model that emulates seismic wave propagation based on collected data. The study reveals a significant increase in stress response of tunnels in the fault-fragmented region, especially near fault misalignment interfaces. The application of seismic-resistant measures has been demonstrated to greatly reduce the structural response of the tunnels. Employing damping strategies in the fault-fracture zone and its vicinity can significantly decrease both the dynamic response of the tunnel and the potential for seismic harm, highlighting the significance of such strategies in the seismic design of tunnels.
