Abstract: Due to the globe warm, lead the permafrost into the shrink and thaw, almost all the various initiatives to protect the permafrost measures were adopted to the actual engineering now. The shading was the one of the main measures, was be used on the embankment side slope on permafrost regions. Contrast with the indoor test data, numerical value analysis result and the field observation, we can draw out the conclusion: The embankment side slope shading measure can reduce the roadbed surface temperature effectively, and limit the embankment temperature elevation obviously, and at the same time it can descend the roadbed artificial permafrost table remarkably. All of this can ensure the road safety and smoothed.
