摘　　要：分析了城市埋地燃气管道泄漏规律、泄漏的燃气在土壤中扩散范围的关键影响因素。对城市排水管道产生的沼气和燃气管道泄漏,在市政地下密闭空间(管廊、排水管道、各类井室等)累积所引发的爆炸和中毒特性进行了研究,提出了避免这些次生灾害的具体措施。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.
