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。
The engineering practice of using control blasting technology to dismantle frame structure industrial plants under complex environmental conditions is introduced. Due to the overhead high-voltage cable bridge at the 020m south of the blasted building, high requirements are placed on the control of backseat, flying rock and air shock waves that will occur during the collapse. The authors succeeded in dismantling the plant through the selection of collapsed plans and the design of blasting parameters.
