This study is concerned with tunnel induced ground surface settlement under seismic actions using PLAXIS 2D V 8.6 Finite Element software with plane strain modeling concepts. Practical construction phases were adopted during the numerical analyses to simulate the actual conditions on site, including...

Explosives require initiation for detonation to produce any explosive effects other than a fire and the initiated detonation wave rapidly converts the solid or liquid explosive materials into a very hot, dense, high-pressure gas. This paper investigates the dynamic response of a reinforced concrete...
