摘　　要：根据相关数据对GB4715—2005标准试验火聚氨酯塑料明火SH3的热释放速率进行确定,进而对以后研究此类火源做出指导.同时,运用FDS以SH3作为火源研究地铁站台区域格栅吊顶对点型感烟探测器响应性能的影响,为以后地铁中设有格栅吊顶场所探测器的安装提供依据.The heat release rate of GB4715--2005 standard test fire polyurethane plastics flame SH3 is studied according to relevant data and a guide for researching such fire is given in the paper. At the same time, SH3 as the fire to research the response performance of smoke fire detectors impact factors of impending type grille ceiling in subway platform area based on FDS is schosen in order to provide basis for how to set up point type smoke detectors in the subway with grille ceiling later.
