摘　　要：介绍了控制爆破技术在复杂环境下的城市高架桥拆除中的运用。结合爆破环境和爆破要求,使用潜孔钻在高架桥上开凿大孔径炮孔,设计合理的爆破参数,采用非电延时起爆网路和有效的安全防护措施。这是大孔径装药技术在城市控制爆破中运用的尝试,为类似工程积累了经验。The use of controlled blasting technology in the demolition of urban viaduct in complex envi- ronment was introduced. According to the condition and requirement of blasting, large diameter blastholes were cut in the viaduct with drill, reasonable parameters were designed, non-electric delay blasting network and effective protection measures were adopted. It was an attempt of large diameter charge technology in urban controlled blasting, and also accumulated experience for the similar projects.
