摘　　要：12个钢筋混凝土筒仓相互连接、结构稳定,因高宽比较小,难以整体向同一方向倾倒。通过预处理将其分割成3组独立的结构群体,通过每组顺序延时起爆,实现连体筒仓向两个方向定向倒塌。在对其进行较为充分预处理的基础上,通过选择合理的爆破切口高度、布孔参数、药量、延期时间和安全防护措施,确保了本次爆破的成功。Twelve reinforced concrete silos were interconnected and stable in structure. It was difficult for them to topple over toward same direction, because ratio of height to width was small. Through pretreatment measures such as dividing them into 3 separated structures and delay initiation them in sequence, directional collapse of these silos toward two directions was realized. On the basis of sufficient pre-treatment, the cut height, blasting parameters, charge amount, delay time and safe protection measures were reasonably selected to ensure blasting demolition of the interconnect silo success.
