摘要(Abstract)：

在15d内采用定向爆破先后拆除4栋7层的住宅楼。这4栋楼具有同样的框架-剪跃式结构。以A楼为例,介绍了立柱爆高的确定、爆破参数的选择、内外墙的预处理以及爆破震动、触地震动、飞石距离的验算。为了降低爆破震动和触地震动,将整个楼房分为4个爆区,采用了导爆管雷管和电雷管相结合的微差爆破网路。
In 15 days,four 7-storeyed domestic buildings were demolished by directional blasting.These buildings have same frame-shear wall and skip-floor structure.Taking A building as an example,determination of blasting height for posts,selection of blasting parameters,pretreatment of inner and outer walls and checks of blasting vibration,touchdown vibration and flying-rock distance were introduced.In order to reduce the blasting and touchdown vibrations,A building was divided into four blasting areas and the millisecond priming circuit combined Nonel detonators with electric detonators was used.
