文章针对爆破拆除烟囱倒地时其对地面的冲击振动形式进行了分析 ;推导出了地下管道对烟囱触地冲击振动的动力响应关系式 ,应用应力波基本理论对冲击振动波对管道薄壁的影响和可能的破坏形式进行了探讨 ;提出了减少烟囱倒塌触地时振动破坏的措施。
In this paper, the impact vibration modes of ground chimney to ground when demolition blasting are analyzed. The dynamic response relationship of underground pipeline to chimney impact vibration is deduced. The basic theory of stress wave is used to analyze the influence of shock vibration wave on the thin- Impact and possible forms of damage were discussed; proposed to reduce the collapse of the chimney vibration damage measures.
