在复杂环境条件下对一楼房进行保护性部分爆破拆除 ,采用机械预切割、折叠定向爆破倒塌的控制拆除方案。本爆破工程采用首阶束状双干线四通小网格复合环多点激发导爆管起爆网路。文中介绍了起爆网络的设计和施工 ,并利用可靠性理论 ,按最大路径原则 ,分析计算了起爆网路的起爆可靠性
In a complex environment conditions for the first floor of a protective building demolition blasting, the use of mechanical pre-cutting, folding directional blasting collapse control demolition program. The blasting project uses the first order beam double trunk four-way multi-grid composite ring multi-point excitonic detonating tube initiation network. In this paper, the design and construction of detonating network are introduced. By using the reliability theory and the principle of maximum path, the detonating reliability of detonating network is analyzed and calculated
