摘　　要：通过试爆选择合理的炸药单耗,为不同尺寸的立柱确定了相应的爆破参数。在不影响施工安全的前提下,对有可能影响楼房倒塌的剪力墙做了必要的预处理。对爆破切口层的主次梁、楼梯梁以及梁柱交接处布置松动孔,随楼层起爆,有利于楼房倒塌过程中结构的解体。爆破中设计了非电交叉复式起爆网路,并利用爆破水幕方法降尘,实践中也取得了预期的效果。The blasting parameters and specific change for posts with different sections were determined through trial blasts. The shearing force wall which may affect collapse of building was shut off in advance on the basis of safe construction. Some blastholes were arranged on primary and secondary beams, stairs and connections of beams and posts on blasting floors. These holes exploded with blasting floor, therefore, the structures could be broken up adequately in course of building demolition. The cross duplicate non-electricity network was designed and water fog caused by blasting was used to eliminate dust in building blasting. The favorable effects were achieved in practice.
