一例砖混结构建筑物爆破拆除失败原因分析

Analysis of Defeat Reason of Blasting Demolition of Brick-concrete Building

砖混结构建筑物由于其结构复杂、稳定性好,在采用爆破技术拆除时如果在设计和施工时不充分考虑其结构特点,出现技术设计缺陷,常常会造成爆破后不倒塌现象,留下极大的安全隐患。通过对一例砖混结构建筑物爆破拆除失败的原因进行分析,阐述砖混结构建筑物爆破拆除时的技术设计和施工作业要点,以供类似工程借鉴。

Owing to its complex structure and well stability,the blasting demolition of brick-concrete building usually occurred non-collapse after blasting and leaved extreme hidden trouble because of deficiently considering the structure character during design and construction. Through analyzing the fail reason of blasting demolition of a brick-concrete building,the key point of design and construction of brick-concrete building blasting demolition was elabora- ted.
