摘　　要：昆明站房高架候车厅长72.65m,宽39.4m,高8.85m。墙体四周设置大玻璃幕墙,屋顶设置采光带,夏季候车室存在过热的可能。通过PHOENICS软件对原设计情况及改进措施进行了数值试验,通过分析不同的四个方案得出在屋顶增加通风口;取消采光带;加大东墙门口面积。为最好的推荐方案,并用PHOENICS模拟出候车室内的温度场、风场的变化情况,推荐方案既可达到良好的室内通风又能保证室内温度低于27℃,完全可以满足候车室内人员活动要求。The high-elevated waiting hall of Kunming railway station is 72.65 meters long, 39.4 meters wide and 8.85 meters high. There are large glass curtain walls all around the waiting hall and on the roof there are day lighting lines. It is likely to be overheated in summer. The software PHOENICS is used to carry out a numerical test on the waiting hall under the original design condition and the improving measures, some advices are given. Through analyzing four different schemes, a solution is gained: increase the number of vents on the roof; cancel the day lighting lines; broaden the gate on east wall. It is the best one of recommended means. The thermal environment and the wind field of the waiting hall are also simulated. Not only the ventilation but also the indoor temperature lower than 27°C is guaranteed, which meets the requirements for the people is activity in the hall.
