Abstract: Based on the finite element model of the tunnel, dynamic response of tunnel is studied influenced by different confining pressure and different surrounding rock types under of blasting vibration under blast vibration load. The results show that when the confining pressure increases, the maximum horizontal and vertical vibration velocity, stress and displacement increase, and the horizontal vibration amplitudes are less than the vertical vibration amplitudes. With the decreasing of the rock type, the vertical v…
