【摘要】 通过对减振沟开挖前后两个阶段爆破振动加速度峰值的监测,采用回归分析的方法,得到两种情况下的萨道夫斯基经验公式。通过对比分析的方法,得到减振沟对振动加速度峰值的减振规律。结果表明,合理的开挖减振沟可有效地降低爆破振动加速度峰值。更多还原

【Abstract】 Peak value of blasting vibration acceleration was monitored before and after damping ditch excavation by means of regressive analysis method to obtain the Sadavski experience formula.The damping rules of damping ditch to peak value of vibration acceleration were obtained by contrastive analysis method.The study results showed that peak value of blasting vibration could be effectively reduced when damping ditch was excavated reasonably.更多还原
