摘　　要：在繁华闹市区成功地进行了一次定向爆破拆除两幢高27m的六层框架楼房。通过采取的严格措施控制了楼房的塌落振动和爆破飞石,使之既不能产生过大的后坐,又不能在倒塌后产生较大的侧向滑移。本文所介绍的爆破技术参数设计及安全防护措施,可为类似工程的实践提供参考。Two 27m high buildings in frame structure, each with 6 storeys, located in downtown area, were successfully demolished by directional blasting. The collapse shock and fragments were well controlled by the use of strict measures, making the buildings has neither over backward collapse nor visible side displacement in the process of its demolition. The blasting parameters and security defence measures presented in this paper offered reference for the similar engineering.
