筒形建筑物爆破拆除参数的选取直接影响到建筑物倾倒的失稳过程、影响到建筑物倾倒时对地面的冲击作用,而建筑物对地面的冲击作用恰恰是爆破拆除应该控制的一个基本因素。本文阐述了筒形建筑物爆破拆除的物理过程,并由此导出最佳爆破参数。对于强度高、厚度大的建筑物,切口长度不宜小于圆周长度的60％,一般必须大于圆周长度的50％。切口长度的大小取决于建筑物的强度、密度和几何尺寸。本文最后讨论了烟囱爆破拆除对地面冲击作用问题,并提出冲量的最小值与烟囱的材料和几何尺寸有关。
The selection of demolition demolition parameters of tubular buildings directly affects the instability process of the dumping of buildings and the impact on the ground when the building is dumped. The impact of the building on the ground is precisely a basic factor that should be controlled by demolition demolition. . This article describes the physical process of blasting demolition of a tubular building and derives the optimal blasting parameters. For buildings with high strength and large thickness, the length of the incision should not be less than 60% of the circumferential length, and it must generally be greater than 50% of the circumferential length. The length of the cut depends on the strength, density, and geometry of the building. At the end of this paper, the impact of chimney blasting on the ground is discussed. It is proposed that the minimum value of the impulse is related to the material and geometry of the chimney.
