摘要(Abstract)：

采用非电多回路网格式起爆网路,一次点火、分段延时起爆,对钢筋混凝土框架-剪力墙筒状结构大厦实现了同向双切口定向爆破拆除。楼体后坐距离小,爆堆高度低,塌落振动小,飞石和粉尘得到有效控制。实践证明,拆除低层承重柱较少的建筑物时,采用同向双切口爆破方式,拆除效果很好,可为类似工程的爆破拆除提供参考。
Initiation network with non-electric and multi-loop grid,one firing,delay blasting was selected to the same direction double incision directional blasting demolition of reinforced concrete frame shear structure tubbiness mansion.The blasting results showed that small recoil distance,low altitude and caving vibration velocity were obtained,and the flying rock and dust were under controlled.Thus proved that the same direction double incision blasting method adopted in the demolition blasting project which had small number of king tower in the low floor could get better effect.It provided a reference to similar project.
