- Abstract:
-
The road disease in permafrost regions is related to the thawing deformation of the underlying per.mafrost, as well as to the weakening the embankment strength caused by freezing-hawing eyeles. In this stud.y, in order to investigate the inluenee of freezing-thawing cyeles on the strength of coarse-grain fill, the inllu.enee of freezing-thawing eyeles on the modulus of resilienee of coarse-grain fill with dilferent water contentswas studied with laboratory experiments. The results showed that, both freezing-thawing eyeles and water con.tent weakened the modulus of resilienee of eoarse-grain soil, which could not be negleeted. With the inereaseof water content of coarse-grain soil, the modulus of resilienee did not deerease rapidly, the reason of whichwas related to the frame slructure formed by coarse grain.
