摘　　要：介绍了地下机械式汽车库的火灾荷载及其可能的最大热释放速率,利用CFD方法对设计的火灾场景进行数值模拟,得到了各工况下汽车库内温度场分布。通过对数值模拟结果的分析,对地下机械式汽车库自动喷水灭火系统的设置、排烟系统设置以及车库结构防火保护提出了一些建议。The fire load and the possible maximum thermal release rate of car fire in underground mechanical garage were introduced. The design fire scenarios were simulated by CFD method and the temperature distribution in the underground garage under different conditions were obtained. Through the analysis on numerical simulation results, some suggestions for fire protection design of underground mechanical garage were puts forward, such as the sprinkler system, smoke exhaust system and structure fire protection.

关 键 词：地下机械式汽车库 温度场分布 数值模拟
