【摘要】 为确定爆破震动衰减规律,通常采用最大振动速度、最大单段药量、布点到爆区中心的距离这3个变量回归计算萨道夫斯基振动速度公式系数。为精细分析爆破振动衰减规律,用单段延时串联起爆网路,结合测试速度图谱的不同时刻最大值、对应单段药量、布点到不同孔位距离,依据一元线性回归原理计算出振动速度公式系数,为爆破振动测试提供了一种精细分析方法。更多还原

【Abstract】 As a rule,to confirm blasting vibration attenuation rule,coefficients of the Sadov’s vibration formula can be regressed with three variables,namely,maximum vibration velocity,maximum charge amount per delay interval,distance between center of blasting area and measurement place.To confirm blasting vibration attenuation rule accurately,coefficients of the Sadovski vibration formula can be gained by use of the unary linear regression theory for per delay consecutive firing,with maximum velocity at different times,corresponding charge amount per delay interval,distance between measurement stationing and hole.A fine analysis method for blasting vibration testing is put forward.更多还原
