摘　　要：对地铁车站进行热烟测试,根据不同排烟工况下站厅、站台的排烟效果,对规范要求的热烟测试方法及排烟控制策略的适用性进行分析。研究表明,存在多个防烟分区的站厅的热烟测试评价标准需细化,站台排烟楼梯口部风速宜控制在3~4 m/s,开启站台端门利用事故风机、排热风机辅助站台排烟的排烟效果优于设置集中排烟管排烟。In this paper, the hot smoke test of subway stations is carried out. According to the smoke exhaust effect of station hall and platform under different smoke exhaust conditions, the applicability of the hot smoke test method and smoke exhaust control strategy required by the code is analyzed. The study shows that the hot smoke test and evaluation criteria of station halls with multiple smoke prevention zones need to be refined. The wind speed at the top of the platform smoke exhaust stairs should be controlled at 3~4 m/s. The smoke exhaust effect of opening the end door of the platform and using accident fan and heat exhaust fan to assist the platform smoke exhaust is better than setting the centralized smoke exhaust pipe.
