| 摘 要： | 针对目前爆破理论比较落后,对烟囱拆除爆破时的倾倒过程研究较少,从烟囱的爆破切口形状出发.建立了不同切口形状下的烟囱倒塌过程的力学模型,分析了切口形状对烟囱倒塌过程的影响,得到了一些有益的结论.

| Abstract: | Due to the actuality that blasting theory is not advanced and that collapse rule is rarely researched when chimney is demolished by controlled blasting,the mechanical models to determine collapse rule were built in this paper when different chimney cut shape was adopted.The influence of cut shape on chimney collapse was analyzed,thus some useful conclusions were drawn. |
