An Analytical Study on Blast-Induced Ground Vibration with Gravitational Effect
A theoretical approach is proposed to investigate blast-induced ground vibration by considering the body force. On the basis of the principle of momentum conservation at the wavefronts, we derived the reflected body waves along the ground surface and the interaction of the body wavefront and ground surface inducing the secondary surface wave that transfers outward onto the ground. Subsequently, the particle velocity on the ground surface was derived, and a parametric investigation was conducted with regard to the effects of horizontal distance from the blast source, embedded depth of the blast source, and material damping onto the ground vibration. Finally, the effect of gravity on the ground vibration was also investigated.
