摘要(Abstract):

介绍了复杂环境条件下,两栋连体楼房需拆除其中一座6层框架结构楼房,而保留另一座相对较弱的5层砖混结构的爆破技术设计和安全防护措施。二连体楼房不预先分离而采取直接爆破拆除的方法,通过精心设计和施工取得了沿保留楼房墙面平行定向倒塌的成功经验,可为类似工程提供借鉴和参考。
The design of blasting scheme and the measures of safety protection in directional controlled blasting of a building in six-storied frame structure separately from its another reserved building in five-storied brick-concrete structure in a complicated environment was discussed in this paper where the way of blasting demolition without preseparation of conjoined building was adopted.Successful experiences for directional collapse in parallel along building walls were obtained by careful design and strict construction.It could offer a reference for the construction of similar projects.
