摘　　要：介绍了采用控制爆破技术在复杂环境条件下拆除框架结构工业厂房的工程实践。由于被爆厂房的南侧 0 0 2m处有架空高压电缆桥架 ,因而对倒塌时会发生的后坐、飞石和空气冲击波的控制都提出了较高的要求。作者通过倒塌方案的选择和爆破参数的设计 ,使厂房拆除获得成功。This paper introduces the practice of demolishing an industrial house with frame structure in complex environmental conditions by controlled blasting. Because the bridge supports of high voltage cable are only 0.02m away from the house to be blasted, strict control of the recoil, flying rocks and airblast is called for. Through correct selection of collapsing sheme and blasting parameters, the house is demolished successfully.
