城市道路隧道空气温度与隧道长度、交通量、通风方式、风速、隧道与地层换热条件等因素相关。在对隧道周边地层的温度场进行分析的基础上,建立了道路隧道内空气换热模型,并对地层与空气间的换热量、汽车散热量、隧道内灯具散热量计算方法进行了分析,推导出了隧道内空气温度的解析解。按照本文推导出的隧道内空气温度计算方法,对武汉长江隧道内空气温度进行了计算,经与实测温度对比,计算结果与实测温度基本吻合。
Urban road tunnel air temperature and tunnel length, traffic, ventilation, wind speed, tunnel and formation heat transfer conditions and other factors. Based on the analysis of the temperature field around the tunnel, the model of air heat exchange in the tunnel is established, and the calculation method of the heat transfer between the ground and the air, the heat dissipation of the vehicle and the heat dissipation of the light in the tunnel are analyzed. An analytical solution to the temperature of the air in the tunnel is deduced. According to the calculation method of air temperature in the tunnel derived in this paper, the air temperature in Wuhan Yangtze River Tunnel was calculated. Comparing with the measured temperature, the calculated results are in good agreement with the measured temperature.
