摘要
介绍钢筋混凝土框架和砖混结构相结合的礼堂办公楼合一的准框架体在复杂环境下定向倒塌拆除爆破。由于待爆楼体的高宽比小,楼体自重不够,爆后解体不够充分并分析其原因,增加混凝土立柱炸高,增大其倾倒力矩。在爆破前用消防车对整个楼体洒水和贮水,降低灰尘。
The directional collapse control-blasting of brick-concrete frame structure is introduced in the complicated environment. In the condition of a low high to width ratio, because of the not enough self-weight, the disaggregation of the building is not enough, we should increase the blasting-high of reinforced-concrete pillar and collapse moment. Watering and reservoir can reduce the dust using the pumper before the blasting.
