爆破振动波叠加数值预测方法
Blasting vibration waveform prediction method based on superposition principle
摘要
Abstract
Based on the superposition principle of seismic waves, a new blasting vibration waveform prediction model was proposed other than the traditional prediction methods founded on data statistics. According to the measured vibration waveforms from single blast holes, the developed model was used to calculate the blasting vibration waveforms at certain locations. In the calculation, the parameters were considered as follows: the position of the recording site relative to each blast hole, the delay time between the detonation of each two blasthole according to the actual initiation network and the measured propagation velocity of seismic wave. The calculated results show that the developed method can be used to predict the blasting vibration velocity peaks, whole vibration waveform, vibration duration and main frequency distribution. And the calculated waveforms are coincident with the recorded ones in the deep hole blasting tests using electronic detonators. It indicates that the developed predication method is reliable for engineering application.关键词
