    Abstract
  • In order to investigate the applicable effect of thermosyphon in permafrost regions along Qinghai-Tibet Highway, 8years'observational ground temperature data were collected from Chuma'er River test site, and the effective radius of thermosyphon was evaluated by taking the horizontal temperature gradient as the index. Additionally, to enhance the temperature-adjusted effect of thermosyphon, extend its application scope and meet the using demand of strong heat absorption of widened subgrade, the observational ground temperature data of the subgrade with XPS insulation board and thermosyphons and the subgrade with rock-crushed interlayer and thermosyphons at Beilu River and Anduo test sites were analyzed. Analysis result shows that the effective radius of thermosyphon after 1year's operation is about 2.3 m, and the influencing range gradually increases with the increase of operational time. Within the first 5 years of thermosyphon operation, the ground temperature obviously decreases, the ground temperature's decreasement around the thermosyphon is over 0.5 ℃, and then, the ground temperature slowlydecreases, which results from the decrease of ground-air temperature difference because of the increase of air temperature and the gradual decay of work motivation of thermosyphon. During8 years of thermosyphon operation, the artificial permafrost tables of thermosyphon subgrades are almost unchangeable because of thermosyphons'continuing refrigeration, while the maximum decrease of contemporaneous artificial permafrost table of common subgrade is about 80 cm. Since June for the subgrade with XPS insulation board and thermosyphons, the temperature difference between top and bottom of XPS insulation board gradually increases, and the maximum value is17 ℃, which effectively mitigates the downward transfer of heat in warm seasons. In 2years'adjustment of subgrade with crushed-rock interlayer and thermosyphons, the maximum decrease of ground temperature is 0.51 ℃.
