    • Abstract
  • Based on the model test data indoors, combined with the numerical calculations and the measured temperatures of air and permafrost,and the test data of roadbed in Fenghuoshan, the protecting effects of the awning on the permafrost table along the road and railway in permafrost regions are compared. The superiority and feasibility of the awning are confirmed. The awning can resist the solar radiation to land surface effectively, and the ground surface temperature can descend 8 ℃～15 ℃, with a maximum difference of 24 ℃.The awning is very important to the safety of roadway.
