摘　　要：采用定向控制爆破方法,拆除复杂环境下的相邻两座烟囱。文章详细介绍了爆破工程的环境条件,对爆破拆除方案进行分析阐述,最后进行工程的安全验算,并给出相应的防护措施。工程实践表明,采用水钻钻孔工艺布孔位置精准、孔深可控,同时采取大孔径对撑布孔处理烟囱内衬效果良好,直接防护及利用地下结构的安全防护措施恰当,实现了精准安全拆除的效果,可为今后烟囱施工提供参考。Oriented controlled blasting method was used to demolish two adjacent chimneys in complex environment.The environmental conditions of the blasting engineering are introduced in detail,and the blasting demolition scheme is analyzed and expounded.Finally,the safety checking of the engineering is carried out,and the corresponding protective measures are given.The engineering practice shows that the position of the hole is accurate and the depth of the hole is controllable by using the water drill drilling process.At the same time,the use of large-aperture holes to treat the lining of the chimney has good effects.and the safety protection measures of direct protection and utilization of underground structure are appropriate,achieving precise and safe demolition,which can provide reference for chimney construction in the future.
