摘要(Abstract)：

通过对两座120m高钢筋混凝土烟囱的定向爆破,介绍了实施爆破拆除的技术措施,重点阐述了爆破切口位置的选取,爆破参数的选择,爆破安全的防护措施等。针对现场环境并结合烟囱爆破拆除中最难控制的定向准确性、塌散长度及触地飞溅防护问题,进行了科学分析和精心设计,并对爆破振动和塌落振动进行了校核。
This paper introduced the implementation of demolition technical measures of directional blasting regarding a demolition of two 120m height reinforced concrete chimneys.The introduction emphasized the localization of the blasting cut,the choice of blasting parameter,the protective measures of blasting security and so on.It also made a careful design and scientific discussion on the issues such as the directional accuracy which was the most hard to control regarding the site environment,collapse length and touch ground protection.And moreover,the paper checked the blasting and collapsing vibration.
