| Abstract: | The leakage rule of urban buried gas pipeline and the key influence factors of dispersion of leaked gas in soil are analyzed. The characteristics of explosion and poisoning caused by sewer gas and leaked pipeline gas accumulated in underground confined spaces, such as pipeline corridors, sewers and manholes are studied. Concrete measures for preventing the secondary disasters are put forward. |
