摘　　要：对武汉市已建成在用的8个地下人行通道的内环境进行测试,测试内容包括通道内的空气温度、空气湿度、壁面温度、照度、风速、壁面导热系数、人流量等数据以及结露现象。武汉地区地下通道严重结露现象主要发生在每年的7月和8月,测试数据说明武汉地区地下通道结露主要是因为地下空间外热湿空气带入的水分。埋深较深和长度较长的通道较容易结露。较大的人流量一方面会增加人员散湿,另一方面也能促进内部空间的空气流通,有利于缓解结露现象。结合相关规范和现场调查数据,给出了武汉地下人行通道内环境质量中相对湿度和照度指标建议值。The indoor environment of eight existing underground pedestrian passages in Wuhan was tested,including air temperature,air humidity,wall temperature,illumination,wind speed,wall thermal conductivity,human flow and dew phenomenon.The serious condensation of underground passages in Wuhan mainly occurred in July and August.The test data show that the condensation of underground passages in Wuhan is mainly due to the moisture brought by the hot and humid air outside the underground space.Deep and long buried channels are easier to dew.On the one hand,larger flow of people will increase people's moisture dissipation,on the other hand,it can also promote the air circulation in the internal space,which is conducive to alleviating dew phenomenon.Based on the relevant specifications and field survey data,the recommended values of relative humidity and illumination index in the environmental quality of Wuhan underground pedestrian passage are given.
