摘要(Abstract)：
爆破振动的影响因素是复杂多变的,不同的爆破影响因素的主次也不尽相同。从岩石内炸药爆轰能量释放形式的角度,结合南非某工程爆破现场实时爆破振动监测数据,对南非新型炸药GIFT和常规炸药CE两种不同炸药产生的爆破振动效应进行分析,得到了两种炸药爆炸引起的地面质点振速峰值,随爆心距变化的衰减函数关系和振动持续时间。结果显示两种炸药爆炸性能的差异,对爆破振动效应的衰减规律和振动持续时间都有很大的影响。
The factors of blasting vibration are complex and variable and the order of primary and secondary of different factors is also different.From the release form of detonation energy of explosive in rock mass,and combining the monitoring results of blasting vibration for a project in South Africa,the blasting vibration caused by Gas Induced Fracture Technology(GIFT) and Commericial Explosive(CE) was analyzed.The attenuation function relation of ground particle vibration peak with the distance to blast source and the vibration duration caused by this two explosives were obtained.The resutls show that the different characteristic of two explosives has largely influence on the attenuation law and the vibration duration of blasting vibration.
