摘要
以一座高48 m砖结构烟囱的成功拆除为实例,介绍了在民房密集区、倒塌场地条件比较恶劣的情况下,砖结构烟囱定向爆破的设计和施工要点,具体来说就是通过开设定向窗及采取覆盖防护、堆砌缓冲堤等措施,确保烟囱倾倒方向的准确及周边建筑物、设施的安全,并对距离爆破点最近处的民房进行了振动监测,为类似工程提供借鉴。
The paper introduces the key points of design and construction for directional blasting of brick-structured chimney based on a successful blast of brick-structured chimney with a height of 48 meters in dense residences and unfavourable col- lapsing environment. To assure the accuracy of chimney collapse direction and the safety of surrounding structures and facili- ties, many measures have been taken such as setting directional windows, covering protection and buffering protection. Vibration monitoring has been adopted for the residence near the blasting point. It can provide reference for similar projects.
