Abstract:
The temperature fields of airfield runway subgrade and road subgrade in the permafrost region of Qinghai-Tibetan Plateau were compared. The subgrade temperature distributions, the temperature variations along depth, as well as the maximum melting depths of subgrades were analyzed. The subgrade temperature field characteristics of wide airfield runway of asphalt concrete pavement were studied. The subgrade temperature distributions, the subgrade temperature variations along depth at different times and the maximum melting depths of middle and shoulder of runway under different pavement width conditions were compared. The expression of subgrade melting depth of airfield runway of asphalt concrete pavement was obtained based on the pavement width and time. Analysis result indicates that there are obvious differences between the temperature fields of airfield runway subgrade and road subgrade in the permafrost region. The subgrade melt nuclear of airfield runway is lower in position, and it is all below the natural ground, as well as the subgrade melt nuclear of road is higher in position. The melt nuclears are all located in the embankment by raising the embankment, which facilitates the construction of temperature control measures like ventilation duct. It shows that because airfield runway has the characteristics like no embankment and wider pavement, the existing research results of road and railway construction in the permafrost region can not be fully applied to airfield runway construction. For the airfield runway permafrost subgrade of asphalt concrete pavement, as the width of pavement increases, the subgrade stability decreases. When the pavement width increases by 1%, the subgrade isotherm of 0 ℃ decreases by 0.17%, the highest temperature of subgrade melt nuclear increases by about 0.46%, and the subgrade melting depth of middle of runway increases by about 0.19%. But when the width of pavement exceeds 35 m, the subgrade melting depth of middle of runway tends to be stable. Compared with the temperature field of middle of runway subgrade, the shoulder is less affected by pavement width, when the width of pavement exceeds 25 m, its subgrade melting depth tends to be stable. The correlation coefficient of expression of subgrade melting depth of middle of runway is 0.988 6, and the relative error is less than 1%. 6 tabs, 47 figs, 35 refs.
