火灾是地铁系统中危害最大而发生频次最高的事故。由于火灾实验具有一定的破坏性,加之地铁运营、安全等因素的限制,以及技术手段的局限,数值模拟被更多地应用到地铁火灾的预测和防控研究中。本文主要论述地铁火灾数值模拟研究的前沿进展,对现有主要的模拟软件和软件中有待完善的问题进行综述和分析,为地铁火灾数值模拟的研究提供参考。
Fire is the most damaging and most frequent accident in the subway system. Due to the destructive fire experiment, combined with the limitation of subway operation and safety, as well as the limitations of technical means, numerical simulation is applied to the prediction and prevention and control of metro fire more. This paper mainly discusses the forefront advances in the numerical simulation of metro fires, summarizes and analyzes the problems that need to be perfected in the existing major simulation softwares and softwares, and provides reference for the numerical simulation of metro fires.
