摘要(Abstract)：

介绍了周边条件不能满足整体定向倾倒的复杂环境下,采用双向三次折叠控制爆破技术对18层电力大厦实施拆除,通过合理选择最佳倒塌方向、开设三个爆破切口、控制起爆延时及设置缓冲堤等安全防护措施,有效地解决了城市中高层建筑爆破倒塌空间受限及爆破振动危害等问题,可为类似工程提供借鉴。
The surrounding conditions can not meet the overall directional dumped in complicated environment.Bidirection-3-times-folding control blasting technology adopted to demolition of 18-storey building was introduced.The best direction collapse was selected,three blasting open incisions,controlled detonation delay and setting buffer embankment protection and other security measures were completed to effectively solve the high-rise buildings collapsed space limited in city blasting vibration damage and other issues.It could provide a reference for similar projects.
