| Abstract: | Our paper has not only analyzed the pat terns of the gro und shock caused by the demolishedchimney, but also deduced the dynamic respo nse relat ionship betw een the subter ranean pipeline and thegr ound vibration. Based on the know ledge o f the st ress w ave, the paper examines the state of the pipelineunder the shock loading , and describes the possible forms o f dest ruct ion. Final ly, the paper pro poses someuseful measur es of reducing the impact s caused by the col lapsing chimney. |
