| Abstract: | 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. |
