| 英文摘要 | The analytical solution of blasting seismic waves induced by cylindrical charge in a viscoelastic half space was lacked. In this study, an approximate analytical solution of this problem is proposed, with the combination of the exact analytical solution of the blasting seismic wave in viscoelastic full space and the reflection coefficients of plane waves in viscoelastic half space. To verify the accuracy of the proposed analytical solution, the finite difference method is employed and the numerical results is found well matched the theoretical analysis. The results indicate that the blast load parameters and the mechanical parameters of medium have predominant impact on the propagation of blasting seismic wave, the vibration attenuation on free surface can be divided into near field and far field according to charge depth. In the near field, the vibration amplitude decreases in the vertical direction but increases in the horizontal direction. In the far field, the vibration amplitude decreases in both the vertical and horizontal directions. (C) 2020 Elsevier B.V. All rights reserved. |
