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 13storeyed frameshear building with a height of 45m in complex surroundings was partially demolished by directional blasting with combination of different cut heights with various delay intervalsThrough selecting reasonable blasting parameters on base of testing blasts,effective pretreatment and protecting measures,collapsing direction and turnover of the building,flying rocks and seismic wave were effectively controlledThe ground vibrations resulted from blasting and touchdown of the building were monitored and the monitoring results were analyzedIn a word,the demolition blasting is successful
