摘要(Abstract)：
介绍了一座异形砖混结构楼房采用纵向延时定向倾倒拆除爆破技术的应用。采用导爆管雷管孔内延时与孔外延时相结合的爆破网路,实现楼房爆破中南北纵向同期延时,使整栋楼房按设计逐步向东定向倾倒。该爆破技术能有效地减小拆除爆破时的最大单响药量,实现结构逐步塌落,从而减小塌落振动。
A special-shaped brick and concrete building was demolished by the application of longitudinal delay and directional collapse blasting technique.This blasting technique was described in this paper.Blasting network of detonator delay in-hole and out-hole was adopted to make the building explosion delay at the same period both in the north and south.Then the whole building gradually collapsed eastward in line with the plan.The blasting technique could effectively reduce the maximum explosive charge of each blasting and made structure collapse one by one,thereby it reduced the collapse vibration.
