摘要
以大浪站为研究对象,建立了地铁车站的物理和数学模型,根据设计条件确定模型的边界条件,分别对地铁车站正常工况和火灾工况的温度场和气流场进行了模拟分析。结果表明:正常工况下,站台层和展厅层的平均温度和气流速度满足设计要求;站厅火灾工况下,站台补风可不开启,站台火灾时,区间风机需开启。
With the Dalang station as object,develops a mathematical and physical model of underground railway station.Simulates the temperature and velocity fields under normal and fire situation based on the defined boundary of deign conditions.As a result,the design temperature and velocity in platform and hall can be maintained under normal condition,the makeup air system of platform can be kept shut under hall fire condition and the tunnel fan needs to be operated under platform fire condition.
