摘要(Abstract)：

待拆除厂房为不平衡的6层钢筋混凝土框架结构,周围环境较复杂。通过采取预处理方式将需保留的筒体与厂房相连部分进行分离,由于精心设计爆破切口和起爆网路,使结构不平衡厂房的重心按预想的方向倾斜,按设计方向倒塌,确保了两筒体的安全。
The demolished factory workshop is a six-storey and reinforced concrete frame one imbalanced in weight.The surroundings of the workshop was very complicated,with a tubby building nearby it and needed to be protected.The demolition started with the isolation of the tubby building from the connecting section of the workshop through pretreatment,and following the employment of carefully designed blasting cut and ignition network successfully made the collapse of the workshop along the anticipated direction.The blasting demolition of the factory workshop successfully protected the security of the tubby building.
