摘要(Abstract)：

针对钢筋混凝土薄壁圆筒连体粮仓群高宽比小、建筑结构稳定、抗弯曲和抗倾覆力强的特点,以河南圆筒粮仓爆破拆除为例,介绍了爆破设计与施工技术要点,设计采用一个爆破切口,通过提高爆破切口高度,在矩形切口底部增加了三角形切口区,爆破取得了圆满成功,为类似工程的爆破拆除提供了一定参考。
According to structural features of the reinforced concrete connecting body cylindrical granary with thin-wall,including low height-wide ratio,stable construction structure,strong bend and overturning resistance,key technical points of blasting design and construction have been introduced based on the blasting demolition case of cylindrical granary.The one blasting cut and triangle blasting cut which added on the bottom of the rectangle cut in order to increase the height of blasting cut have been used.The good blasting effect was obtained and relevant experience could provide a reference for similar projects.
