Abstract

Terrorist actions and defacements have become one of the widest threaten for humans and structures. Underground tunnels can be used as shelters against blast actions, so it is very important to study their behavior under blast loads. The safety of these tunnels is lean because of the lack of suitable ways to discover these events early. Techniques are essential to quantify the resistance of underground structures against blasts as a protection and to calculate the risks causing by the failure of their elements. The appropriate advanced methods could be experimental, numerical, or a mixture of both. The experimental work is limited because of the cost and complication, and so numerical analysis is suitable for blast study in addition to available experimental tests. Ways should be suggested to protect shallow and deep tunnels against the surface and internal blast loads. Studies should use numerical simulation of a tunnel buried in a saturated soil profile to imitate real-world conditions.
