摘要(Abstract)：

待拆四联体钢筋混凝土结构筒仓群,高宽比接近1。爆破前通过对筒仓群进行预切缝,使其成为相对独立结构;采用秒差多段延期爆破方案,使两两独立的筒仓分别向南、北方向倒塌。文中论述了爆破设计方案、爆破参数和切口高度的确定以及起爆网路的设计与施工等。
The four interconnected reinforced concrete silos to be demolished have relatively small ratio of heighttowidthBefore blasting,the silos were cut and divided into two separate structuresBy use of seconddelay blasting,the two separate structures were made to collapse to the south and north respectivelyIn the paper,the design of blasting scheme,the determination of blasting parameters and cut height,blasthole pattern and blasting network were discussed
