| 摘 要： | 针对目前爆破理论比较落后,烟囱爆破拆除时仅仅靠经验确定爆破切角大小和切口高度的现状,从砖烟囱的爆破切口形状出发,建立了确定砖烟囱选用不同切口形状时的切角大小和切口高度的数学模型,分析了切口形状对爆破切角大小和切口高度的影响,并结合工程实例对建立的数学模型进行了分析和讨论.

| Abstract: | In view of current situation that blasting theory is not advanced and that cut angle and cut height are determined only by experiences when chimney is demolished by controlled blasting, this paper establishes a mathematical model to determine cut angle and cut height when different chimney cut shapes are adopted. The author combines an engineering example with the model to analyze and discuss the model in detail, and draws some useful conclusions. |
