夏热冬暖地区地下交通枢纽内部环境实测研究

Measurement on indoor environmental quality of underground transportation hubs in hot summer and warm winter zone

对深圳市福田站枢纽及深圳北站枢纽进行了冬季及夏季环境实测,得到枢纽内部环境质量现状。通过问卷调查的形式对枢纽内乘客的热感觉、热舒适等进行了调查,采用综合评价方法分析了当前环境质量存在的不足。结果显示:两枢纽内部综合环境较好,乘客热环境满意率在70%~80%之间;两枢纽内仍存在一定的环境营造问题,部分功能区有单项参数不满足相关规范要求;可以通过营造夏季从站外到站内空气温度逐渐降低的温度梯度环境、增设遮阳装置、合理组织人工照明和自然采光、在壁面增设消声材料等措施对枢纽内的物理环境进行优化。

Through the environmental measurement of Futian Station Hub and Shenzhen North Railway Station Hub in Shenzhen in winter and summer,the environmental quality status in the hubs is obtained.The thermal sensation and thermal comfort of passengers in the hubs are investigated in the form of questionnaires.The deficiency of current environmental quality is analysed by the comprehensive evaluation method.The results show that the comprehensive environment inside the two hubs is good,and the thermal environment satisfaction rate of the passengers is between 70%and 80%.There are still some environmental construction problems in the two hubs,and there are individual parameters in some functional areas that do not meet the requirements of the relevant specifications.The physical environment in the hubs can be optimized by creating a temperature gradient environment in which the air temperature decreases gradually from outside to inside the station in summer,adding sunshade devices,reasonably organizing artificial lighting and natural lighting,and adding anechoic materials on the wall.
