Taking the Sichuan-Tibet highway for example, comprehensive consideration many actual meteorological factors such as solar radiation,air temperature,wind velocity and landform, Site selection observation section temperature field and the pavement on deformation of roadbed measured.Through the research and analysis of measured data for natural surface, roadbed midline, slope geothermal change characteristics. Analyzed the asphalt pavement, route toward, altitude and landform on embankment temperature field d...
