摘　　要：介绍了13层、高45m的框剪结构楼房部分爆破拆除,其结构和环境复杂。采用了爆破缺口高度差、多段微差爆破时间差相结合的定向倾倒措施,通过试验炮,选择了合理的爆破参数,进行了有效的预处理及防护,使楼房爆破时倾倒方向、触地后的翻转、飞石、地震波等都得到了有效控制。对楼房爆破及倾倒触地产生的震动进行了监测、分析。爆破很成功。A 13storeyed frameshear building with a height of 45m in complex surroundings was partially demolished by directional blasting with combination of different cut heights with various delay intervalsThrough selecting reasonable blasting parameters on base of testing blasts,effective pretreatment and protecting measures,collapsing direction and turnover of the building,flying rocks and seismic wave were effectively controlledThe ground vibrations resulted from blasting and touchdown of the building were monitored and the monitoring results were analyzedIn a word,the demolition blasting is successful
