Abstract
The blasting load induced by the explosion of the powder generation the vibration of the ground and affects on nearby ground and underground structures. The structures are possibly damaged and it may create the social problems such as noneconomic construction due to the delay of the construction period especially in urban areas. Therefore, the stability of the nearby structures need to be evaluated. In this study, the stability of the tunnel is estimated and examined by the analytical solution and by using $FLAC^{2D}$ which is one of the programs based on the finite difference analysis.
