摘要(Abstract)：
为了解高大钢筋混凝土烟囱在倾倒过程中不同爆破切口位置处预留支撑体及切口上、下部筒体的破坏过程,采用高速摄影技术对其进行了观测。通过对比分析,得到了它们在倾倒过程中的破坏规律,为类似爆破工程的设计和参数选择提供参考。
To understand the demolition processes of pre-reserved support body and the cylinder which was located up and down blasting cut during collapse processes of tall reinforced concrete chimneys with different blasting cut positions,high-speed photography technology was adopted to observe their different moment pictures.The demolition laws of pre-reserved support body and the cylinder which was located up and down blasting cut during collapse process were obtained by contrast and analysis.All of which can be used as reference for the design and the preferences of the similar blasting project.
