拱形特殊大厅的控制爆破拆除

Controlled Blasting of a Arched-structure Special Hall

主要介绍了湖南大学新技术大厅这座典型“四无建筑”拱形结构的控制爆破拆除方案、药孔参数确定、装药量计算和网路设计。

The new-technology big hall built in 1958 is one of the two arched-buildings in Hunan university.It's typictal 'four nils' building that contains no steel, no wood, no cement and no tile. About 2 012 holes, 2 250 detonators and 117 kg explosive were used to blast the hall on September 17.2001. The desired results were completely achieved. This paper mainly introduces the program of controlled blasting, the choice of hole parameters, the charging amount and the design of network.
