摘要(Abstract)：
本文从爆破震动影响因素入手,介绍了点爆源爆破震动的特点,分析了微差间隔时间、测点距爆区距离、药量分布等爆破参数对爆破震动的影响,用实测爆破震动波形论证了多段微差爆破时,爆破震动强度由微差间隔时间、测点距爆区距离、各段药量分布等爆破参数联合作用决定。当这三种参数达到最佳"匹配"时,就能达到最佳降震效果。
Starting with the influence factors of blasting vibration,this paper introduced the characteristics of blasting vibration from point explosion source,analyzed the effects of such blasting parameters as millisecond delay interval,measuring distance and charge distribution on blasting vibration,and demonstrated, from the measured wave shapes, that the intensity of a blasting vibration is determined by the joint effect of the above-mentioned parameters in the case of multi-interval millisecond blasting.When the optimal matching between the above three parameters is obtained,the best results of vibration reduction can be achieved.
