摘　　要：本文讨论了高耸构筑物在复杂环境中爆破拆除时,爆破倒塌方案的选取、爆破切口形式和起爆系统的设计、爆破飞石的控制、爆破振动防控处理等各个环节的特点和处理方法,并结合某厂45 m烟囱爆破拆除实例,介绍了该类建构物在复杂环境下爆破拆除时各环节的处理过程。实践表明,复杂环境下高耸构筑物通过周密的设计和严格的防控措施是能有效控制爆破危害,取得良好的爆破效果的。The paper discusses the characteristics and treatment methods of various links such as the selection of blasting collapse schemes,the design of blasting cutouts and initiation systems,the control of blasting flying stones,and the control of blasting vibration during the blasting and demolition of towering structures in complex environments.Taking the blasting and demolition of 45m chimney in a factory as an example the process of each link during the blasting and demolition of this type of structure in complex environments is introduced.The practice shows that blasting hazards towering structures can effectively control through careful design and strict control measures in complex environments.

关 键 词：高耸构筑物 拆除爆破 爆破振动 烟囱拆除
