连体楼房的控爆拆除

介绍了连体楼房爆破拆除6层框架结构，保留5层砖混结构楼房的爆破方法和爆破效果，阐述了在环境复杂，工期紧的条件下，充分利用楼房的结构特点，不采用预处理分离，而直接爆破拆除的难点和解决方法，通过精心设计和施工，取得了沿保留楼房交界面平等定向倒的成功经验，对于解决复杂环境条件下，楼房爆破时的定向，爆堆扩涨和后座问题，具有一定的参考和使用价值。

Demolishing Body -connected Building by Controlled Blasting

This paper presents methods and effects of demolishing two body-connected buildings of which one part is six-layer frame structure to be detonated and the other part is five-layer mixed-brick structure. Subjected to the condition of complex surrounding and short time limit for the project, this paper describes the difficulties of detonating directly by fully utilizing structural characteristics without choosing separation during preprocess and their solutions. Successful results are obtained by elaborate design and operation, that is, after blasting the six-layer building falling along the wall parallel to the five-layer protected building. It is auseful reference to the questions of designation of the collapse direction, blasting ruin's expansion and backlash under the complex surrounding.
