复杂环境中双层烟囱定向倒塌爆破

DIRECTIONAL DEMOLITION BLASTING OF TWORINGCHIMNEY IN COMPLICATED ENVIRONMENT

烟囱拆除爆破报导很多，但多数文章只描述了烟囱外壁定向爆破技术方案，很少提及内衬的处理。本文总结了烟囱拆除中对内衬的处理方法，在烟囱定向倒塌控制爆破基础上探讨了一种内衬处理法，并从理论上进行了力学分析，希望能为今后类似工程积累一些经验。

A lot of practical examples on demolition blasting of chimney has been reportedThe treatment scheme of chimney wall was only described in most papers,seldom the treatment method of chimney lining ringThis article goes further into the treatment of chimney lining ring on the basis of directional demolition blasting of chimneyAt the sametime,the treatment way is theoretically analyzed on the basis of mechanicsIn this paper,several treatment ways of chimney lining ring as well as its good and weak points are summarizedIt is hoped that this paper can accumulate some experience for the similar engi neering in the future
