摘要(Abstract)：

介绍了上钢一厂温藻浜中取水口旧沉井的爆破拆除方法。设计采用孔内高段延期雷管、孔外低段延期雷管一次引爆的微差爆破。文中还介绍了采用气泡帷幕、控制单段药量等措施减弱水中冲击波保护邻近建筑物的方法。
In this paper,blasting demolition of an old open caisson of water intake in Wenzao river within Shanghai No 1 Steel Works was introduced The millisecond blasting method with long delay out of hole and short delay in hole detonators and one through initiation was adopted in blasting design In addition,some technological measures to be used for damping of shock wave in water and protection of nearby buildings,such as air bubble curtain and controlled charge weight per delay interval, were outlined
