以长大隧道水泥混凝土路面为研究对象,依托广东省某高速公路长大隧道段为试验路段,在夏季最高温度时段和冬季温度最低时段对隧道内环境温度和湿度进行测试与分析,采用Origin软件对测试数据进行绘图拟和,总结隧道内环境温度变化的特点。根据长大隧道内温度的实际情况,在通车后对隧道温度再次进行测定,对于影响隧道路面温度的各影响因素进行分析,确定隧道内各个测点的最大温差,总结隧道内温度在各因素影响下的变化规律,并对其原因进行分析,确定长大隧道内的温差较小的水泥混凝土路段可适当加长板长,结论可供长大隧道水泥混凝土路面设计参考。
Taking the long and narrow tunnel cement concrete pavement as the research object, relying on the tunnel section of a highway in Guangdong Province as the test section, the ambient temperature and humidity in the tunnel were tested and analyzed in the highest summer temperature season and the lowest winter temperature season. Origin software Draw the test data fitting and summarize the characteristics of the tunnel temperature changes. According to the actual situation of the temperature in the long tunnel, the tunnel temperature is determined again after the traffic is opened. The influencing factors of the tunnel pavement temperature are analyzed to determine the maximum temperature difference of each measuring point in the tunnel. The temperature in the tunnel is summed up under various factors And the reasons for the analysis of the tunnel to determine the temperature difference between the smaller cement concrete sections may be appropriate to lengthen the length of the board, the conclusions for the long tunnel cement concrete pavement design reference.
