摘要(Abstract)：

介绍了闹市区一座V形框架结构楼房的爆破拆除。在综合考虑楼房结构特点和环境条件的基础上 ,采用了同层断面阶梯形分段、不同层以高差与时差相结合的爆破设计方案 ,这一起爆顺序能有效地利用结构自重控制楼房的坍塌范围。同时介绍了三维非电导爆管起爆网络形式。这些方法对类似楼房的拆除爆破设计具有参考价值。
In this paper,blasting demolition of a V shape frame building in a downtown area is introduced Based on analyzing the structural features and surroundings of the building,a blasting scheme of using a detonating sequence of “ladder”type for the same floor and a detonating sequence of combining height difference with time difference (half second delay) for different floors is adopted This detonating sequence can effectively control the collapsing distance of the building by its potential energy At the same time,a three dimensional ignition network composed of NONEL system is presented These are useful for blasting demolition design of similar buildings
