摘要
针对复杂环境下240m高钢筋混凝土烟囱定向爆破拆除项目,通过采用延时爆破技术、开挖减振沟和铺设黄土缓冲垫层等一系列防护措施对振动进行控制,并对爆破振动进行了监测分析,有效控制了爆破振动的影响,减振效果显著,可为同类拆除爆破工程提供参考。
The blasting demolition project of 240m high reinforced concrete chimney in complex environment was introduced. The vibration was controlled through a series of protective measures such as delay blasting technology, digging damping ditches and laying loess cushions. The blasting vibration monitoring data was analyzed also. Affects of blasting vibration were effectively controlled and the effect was significant. It could provide a reference for similar demolition blasting engineerings.
