摘要: Abstract This study numerically estimates the thermal characteristics of cinderblock interlayer embankments in permafrost regions. The wind flow within are tested by tunnel experiment. results, as well heat and mass transfer theories, used to develop a conceptual numerical model without with ventilated ducts. is conducted evaluate cooling capacity expressway results indicate that embankment ducts enhances increase thickness. under embankment, however, still warmer than natural ground surface. warming can be offset when added top interlayer. Therefore, an effective measure ensure stability warm
