| 摘 要： | 介绍了某室内体育训练馆的爆破拆除方案及施工技术.该训练馆两侧为6层框架结构,中部为3层高框架结构,3层以上为钢结构网架.两侧6层与中间部分有施工缝.训练馆长109.4 m,宽32.9 m,高27.8 m,建筑面积约14 895.36 m~2.采用"向东定向倒塌"的爆破方案拆除,即自东向西逐排起爆.起爆后,场馆迅速向预定方向倾倒,倾倒过程很快,主体结构充分解体.爆破后对爆堆进行测量,场馆整体前冲11 m,两侧6层部分向左右各坍塌3 m,6层部分后侧后座3 m,中部3层部分后座1.8 m,中部爆堆高度8 m,两侧爆堆高度5 m.爆破飞石、振动未对周围建构筑物产生影响.爆破取得圆满成功.
