Influence of the Step Elevation on Blasting Seismic Wave

Abstract:

Elevation effect is an important content of the research on propagation law of blasting seismic wave. Based on the numerical simulation and theoretical analysis, the inducement and characteristics of elevation effect are revealed. The results indicate that vibration amplification effect is induced in a certain elevation. The amplification factor doesn’t increase monotonously. Amplification and attenuation effects on blasting vibration velocity exist simultaneously. According to the data analysis and theoretical analysis, a prediction model of vibration velocity on step topography is put forward.
