Seismic Behaviour of Double Arched Tunnel: A Review

Major earthquakes will cause multi-hazard issues for tunnels. Yet, advantages associated with it in terms of sustainability, time, land and fuel saving have made tunnels a vital option in modern cities. Double-arch tunnels are generally accepted for their effective and economical solutions as they have significant advantages in adjusting to the characteristics of the region and environmental safety. Experimental, numerical and analytical studies had been conducted by the researchers to understand its static and dynamic behavior. In the present study, authors have categorized and critically summarized the researches on double arch tunnel. It is essential for platform of higher research and development in this field.
