facing of embankment
1.Results showed that the temperature distribution of the traditional embankment was asymmetrical; the asymmetrical status was changed after ripped-rock revetment was installed and the soil under the ripped-rock was cooled obviously; the ripped-rock revetment could cool embankment and adjust the temperature difference between the north-facing slope and the south-facing slope; the ripped-rock revetment was an available technique to protect embankment from thawing settlement and longitudinal cracks in permafrost regions.
