摘要(Abstract)：

介绍了采用定向爆破和双向折叠爆破技术成功拆除20层剪力墙结构楼房的工程实例。详细论述了爆破切口设计、炮孔和装药参数、炮孔布置、预处理、起爆网路和起爆顺序,以及爆破安全分析和安全防护措施。总结分析了工程施工过程中的经验与教训及几点体会,为类似工程提供参考。
The practical example of successful demolishing 20-storey building with shear wall structure by directional and bidirectional folding blasting was introduced.Besides,design of the blasting-cut,parameters of blast-hole and charges,blast-hole layout,pretreatment of blasting-cut,priming circuit and blasting sequence,analysis of blasting safety and security measure were detailedly discussed.Experience and lessons about this project were summarized and analyzed.The paper provides reference for the similar project.
