摘　　要：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 。Under complicated conditions, a building was partially demolished through controlled blasting. Mechanical pre-cutting was carried out before the building was collapsed by folding directional blasting. In the blasting case, a non electric initiating network was applied which was multi point detonated at different spots,had double trunk line in first stage,bunched connections and closed loops with small reseaus formed by four vents.This paper gives a description of the design and construction of the initiating network. The initiating reliability of the network is analyzed based on the reliability theoty and the maximum path principle.
