Response Spectrum Analysis of Surface Shallow Hole Blasting Vibration

Based on analysis of a Series of blasting vibration data, the response spectrum characteristics of surface shallow blasting vibration was analyzed and studied. The curve of blasting velocity response spectrum has more peaks with periodic changes, but when on a certain period of great value, the curve shape of the velocity response spectrum is parallel with the periodic axis. The curve of acceleration response spectrum has a similar attenuation law as the velocity response spectrum, but attenuation of the velocity response spectrum is faster. The curve of displacement response spectrum, on the contrary, has a increasing trend with periodic increasing after a post-peak. The blasting response spectrum has a faster speed of attenuation than a earthquake and the curve of blasting response spectrum has a exponential decay.
