摘　　要：地铁车站的环境质量关系到车站内人员的生理健康,现今已引起了人们的高度重视。然而,目前许多地铁车站自身内部环境监测系统存在监测项目少、测点布置稀疏等问题,并不能全面反映地铁车站内部环境质量随时间、空间及通风条件等因素的变化规律。通过在某深埋车站内布置综合环境监测网络,实现了对于环境质量主要指标(温湿度、空气成分及放射性元素氡气)的持续实时监测。通过对监测结果进行统计分析,获得了上述环境质量指标随时间和空间的变化规律,明确了影响地铁车站内部环境质量的关键因素。监测结果表明:该车站主要环境指标大部分时段内满足相关标准要求,放射性元素风险较低,环境质量处于较好的状态;受车站通风空调设备分布的影响,车站内不同区域和不同高度的环境略有区别;环境质量受人员活动和车站通风空调设备工作状态等因素的影响。The environmental quality of the metro station is related to the physical health of the people in the station,which has attracted people’s attention.However,at present,many internal environmental monitoring systems of metro stations have problems such as few monitoring items and sparse arrangement of measuring points,which cannot fully reflect the change law of internal environmental quality of subway stations with time,space and ventilation conditions.Through the layout of an integrated environmental monitoring network in a deep buried station,the continuous real-time monitoring of the main indicators of environmental quality(temperature and humidity,air composition and radioactive element radon gas)is realized.Through the statistical analysis of the monitoring results,the variation law of the above environmental quality indicators with time and space is obtained,and the key factors affecting the internal environmental quality of the metro station are clarified.The monitoring results show that the main environmental indicators of the station meet the requirements of relevant standards in most of the time and the risk of radioactive elements is low,and the environmental quality is in a good state.Affected by the distribution of ventilation and air conditioning equipment in the station,the environment of different areas and different heights in the station is slightly different and the environmental quality is affected by factors such as personnel activities and the working status of station ventilation and air conditioning equipment.
