摘要
介绍了100m高钢筋砼结构烟囱的爆破拆除。重点论述了爆破切口的方案设计、爆破参数的选取,对减少触地振动及二次飞石危害的控制制定了有效的防护措施,确保了周围建筑物的安全,对同类工程有借鉴意义。
The present paper introduced the demolition of a 100m height reinforced concrete chimney by directional blasting in terms of its emphases on elaboration of the scheme design of blasting cut,the selection of blasting parameters as well as the determined effective defencing measures of touchdown vibration reduction and secondary flyrock damage control. The blasting secured the surrounding buildings and could be a valuable reference consuling for the engineering of the like.
