摘要
介绍了复杂环境下11层违章楼房定向爆破拆除的方案及参数。将楼房底部设计成三角形爆破切口,对立柱采用梅花形和之字形布孔,单孔装药量100g,通过孔内孔外延时相结合的方式,实现延时爆破和定向倒塌,并分析了框架楼房在空中解体的原因,对同类工程爆破参数的选取具有一定的参考意义。
The scheme and blasting parameters of directional blasting demolition of an illegal ll-storey frame building under complicated environment were introduced. A triangular cut at the bottom of the building was designed, plum-blossom-shape and zigzag-shape hole arrangements were adopted in the col- umns,each hole was charged with 100g explosive and the delay in holes and out of holes was utilized, which realized delay blasting and directional collapse. The reasons for disintegration of the building in the sky was also analyzed. It has a certain reference for the selection of blasting parameters in similar projects.
