摘要
待爆破拆除的楼房为13层框剪结构,整体稳定性较好。为了使楼房爆破后解体充分,本工程采取双切口单向折叠倒塌爆破方案,对楼房的剪力墙进行充分预处理,并采用分区分段自上而下的复式起爆网路,爆破达到了预期效果。文中介绍的爆破参数选择、起爆网路、预处理及安全防护等措施,可供类似工程参考。
The building to be demolished was a 13-storey one of frame and shear-wall structure,with good integral stability.In order to make the building disaggregate thoroughly,one-way and double incisions folding collapse blasting method was used,with the shear wall pretreated thoroughly and be ignited in stages top down by dual blasting network.The result showed that blasting design met the demolition requirement.For presenting the effective blasting the paper discussed in detail the blasting parameters,priming circuit,pretreatment and safety technological measures.
