Artificial Blasting Vibration Response Test and Analysis Based on Cottage Construction of Brick Structure
The old oilfield in eastern China has conducted several rounds of seismic exploration. Artificial blasting inevitably layout into town and city building dense area. Quaternary alluvial plains in loose sand, the local large brick structure housing affordability study with artificial explosives directly related to the optimization of blasting parameters. On the basis of a large number of focal blasting venue, housing vibration test data, combined with the near-surface structure and brick structure housing construction characteristics. It focused on analysis different explosive source caused by blasting parameters venues and housing vibration displacement, velocity, acceleration amplitude, frequency characteristic parameters, duration, and vibration direction, summed up the venues and housing vibration response, attenuation relationship, housing construction vibration characteristics and seismic performance. The results show that, depth change of the blasting based on the ground, housing peak attenuation impact, not changes in dose. Vibration velocity, acceleration, displacement exists obvious amplification effect at 130 m and 230 m.
