摘　　要：采用预处理的办法将某大型水泥厂旧厂房分割成3组独立的结构群体,分组顺序延时起爆,向3个方向倾倒的“同一建筑异向倾倒方案”,并同时采用分组延时爆破、铺设减震垫层和开挖减震沟,显著降低了触地爆破震动,达到预期目的。Some pre-treatment measures are used in a large cement factory building such as dividing them into 3 separated structures and priming them in sequence, so three different directional collapsing of the same construction is realized. In addition, the ground vibration resulted from the collapsing of the interconnected silos can be reduced remarkably by using the delay blasting, laying a vibration damped pad and excavating a vibration-separated ditch. The desired blasting results were achieved.
