摘要
云南省安宁市世贸广场地下室开挖项目周边环境复杂,设计采用导爆管网路逐孔起爆技术以降低爆破振动.为了研究导爆管网路不同的传爆方向对爆破振动的影响,在爆破区域周围四个方向设置不同的测点,进而对大量的逐孔爆破进行振动监测.通过振动数据回归分析:导爆管网路传爆正方向的震动强度最大,反方向的震动强度最小,左侧与右侧方向的震动强度相当,并用统计方法总结出各方向的振动数值百分比.
The surrounding environment of Anning City World Trade Plaza basement foundation pit excavation project is very complexity,designed to use connecting to the detonating network with by-hole detonation techniques to reduce blasting vibration. In order to study the different booster direction to the effects of blasting vibration of detonating network in this paper,by setting different measuring points of the four directions around the blasting area,then Monitoring a large number of by-hole blasting vibration. By regression analyzing vibration data,the detonating network booster opposite direction vibration intensity is maximum,the positive direction of the vibration intensity is minimum,being left direction and being right direction of vibration intensity is quite. And use statistical methods summed up the direction of the vibration numerical percentage.
