摘  要:火焰是危险的，而火焰传播能够引起更大的危害。火焰的产生和传播是有条件的，在封闭或半封闭空间更容易实现，如管道。?11·22?黄岛管道爆炸事故向人们展示了管道火焰的危害。本文通过研究地下排水管道甲烷-空气预混燃烧火焰传播，利用Fluent软件进行数值模拟，并对模拟结果分析，得出地下排水管道甲烷-空气预混燃烧火焰在不同条件下的传播状态和对外部空间的影响。本研究可以为管道爆炸事故的预防和应急措施的制定提供理论指导，具有一定的现实意义。

Abstract: The flame is
dangerous, and flame propagation can create more damage. However, the
generation and propagation of the flame is conditional and it's easier to
realize in a closed or half-closed space such as pipeline. That '11.22' Huangdao
pipeline explosion accident showed damage of the flame in a pipeline. By
studying the flame of methane-air premixed in underground drains using Fluent
software for numerical simulation and analyze that results. This article draw
the flame propagation state of methane-air premixed in underground drains in
different conditions and the impact on external space.
