摘要
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。
Our paper has not only analyzed the patterns of the ground shock caused by the demolished chimney, but also deduced the dynamic response relationship between the subterranean pipeline and the ground vibration. Based on the knowledge of the stress wave, the paper examines the state of the pipeline under the shock loading, and describes the possible forms of destruction.Finally, the paper proposes some useful measures of reducing the impacts caused by the collapsing chimney.
