摘要
介绍了爆破拆除一薄壁钢筋混凝土水塔的实例。针对薄壁这一特点 ,利用分析法计算爆破切口长度。定向口采用组合形式 ,以增大爆高。从炸药能量主要用于介质的剪切、破碎的角度 ,计算单孔装药量。
In this paper, an actual example on demolishing a water tower with super thin reinforced concrete wall by blasting method is introduced. For the feature of super thin wall, the length of a blasting cut is calculated by use of an analysis method. A directional opening of combined type is adopted so as to increase its height. From the angle that the energy of an explosive is used for shearing and crushing of a medium, the charge weight per blasthole is calculated. These views are available for reference for blasting demolition of similar structures.
