摘要
从岩石内炸药爆轰能量释放形式的角度,结合现场实时爆破振动监测数据,对比分析2种不同炸药性能的炸药产生的爆破振动特性,并对质点振动速度峰值的衰减规律及爆破振动持续时间进行回归分析。结果表明:除单响炸药量和爆心距,炸药自身性能对爆破振动效应的衰减规律和振动持续时间也有很大影响。
From the detonation energy release form of explosive in rock mass,the blast vibration caused by two different explosives was analyzed by combining the site monitoring results.And the two factors were regressively discussed： the attenuation of the peak particle vibration velocity with the distance away from the blast source;the vibration duration caused by these two explosives.The results show that apart from the explosive amount per delay and the distance from the blast source,the different properties of explosives have remarkable influences on the blast vibration attenuation and the vibration duration.
