摘要(Abstract)：

介绍了复杂环境条件下104.1m高剪力墙结构楼房爆破拆除,详细阐述了三个大切口的定向控制爆破技术的应用。采用蝶式切割机对剪力墙进行了预处理,重点论述了切口位置、爆破参数,以及防止爆破振动、塌落振动、爆破飞石等安全防护措施,为类似工程积累了实践经验。
Successfully blasting demolition 104.1m high building with shear wall structure was introduced under complex environment.Application of directional controlled blasting technique with three large cutting was detail discussed.Shear walls were pretreated by cutting machine with butterfly shape.Location of cutting 、basting parameters and security measure of preventing blasting and collapsing vibration and blasting fly-rock were mainly discussed.It provides practical experience for similar projects.
