the shocking safety distances for blasting with various charges and safe charge for specific distance are both determined according to the particle vibration velocity safety control standard.
根据质点振速的安全控制标準,确定了不同药量爆破的震动安全距离,以及确定距离的安全药量。
based on practical application, the paper proposes a simple method with allowed velocity(considering frequency) taking place the single particle vibration velocity to distingu…
并针对现场应用,提出采用简单易行的计频允许振速代替单一的爆破质点振动速度来判别爆破安全标準。
through contrasting and analyzing, the particle vibration velocity were forecasted by the orderliness formula of attenuation of blasting earthquake wave is precise relatively.
经对比分析,所得爆破地震波衰减规律公式预测的质点振动速度具有较高的精度。
an optimized predicting scheme about particle vibration velocity has been put forward, a calculation model has been built, and a computer program has been tailored relevantly.
