خلاصه مقاله:

in this paper earthquake dynamic effect on continues porous media for shallow tunnels will be discussed via numerical method and parameters of depth and wave impact angle . The vibrations scattering effect of earthquake -induced on urban tunnel such as subway was discussed. during of earthquake incidence underground structures will be damage on two forms. vibrations of earthquake -induced and ground -rupture are two main reasons of these damages. earthquake vibrations can effect on underground structures in subject of longitudinal and transverse waves therefore different deformations will occur due to these vibrations.
