摘要
介绍在复杂环境下 ,对一特殊结构大面积厂房采用横向逐跨坍塌爆破拆除的方案。为保护地下人防在爆破时不受损坏 ,采用保留底层底部一定长度的立柱不钻孔的方法对立柱的外覆钢筋和角铁进行预切割等一系列技术措施 ,保证了该厂房的爆破成功。
In a complicated environment, a large workshop with special structure collapsed transversely span by span was blasting demolished. To protect underground civil-air-defence in blasting, a certain length of bottom columns of first floor without drilling holes were reserved. Also the exterior reinforcing bars and angle irons of columns were cut in advance. Such technical measures guaranteed successful blasting of the workshop and can be used as a reference in similar explosive projects.
