    Abstract
  • To clarify the characteristics of uneven settlement and deformation of rockfill ventilated roadbed in plateau freeze-thaw areas, relying on the new highway project of G219 in the Karakorum Mountain area of Xinjiang, the temperature change and settlement deformation of rockfill ventilated roadbed were monitored in real-time by temperature sensors and settlement monitoring. The results show that the rockfill ventilated roadbed hinders the heat transfer from the inside of the road, and with the increase of the filling height, there is an obvious temperature lag at the base of the ventilation roadbed, which reduces the overall settlement deformation of the roadbed and slows down the sunny-shady slope effect.
