摘要(Abstract)：
采用定向爆破方法拆除11层钢筋混凝土框架楼房。由于立柱的布筋情况不明,通过爆破试验确定了炸药单耗,针对不同的立柱尺寸确定爆破参数。为了有利于结构解体,在5层以上的部分大断面柱体上和梁柱节点处也布置炮孔。文中还介绍了起爆网路、安全防护措施及爆破效果。
An 11 storeyed reinforced concrete frame building was demoli shed by directional blasting metho d Due to unknown bar reinforcement ,a specific charge was determined through trial blasts and the blasting parameters were designed in the light of different posts So me blasthol es were arranged in partial large sectional posts and beam post join ts over fifteenth floor,thus being favorable to structural disintegra tion In addition,the firing circui t,safety precautions and blasting results were introduced in this pa per
