Based on in-situ monitoring of the duct-ventilated embankment

the crushed rocks embankment

the embankment of crushed rock slope protection

the thermal-insulation treatment embankment and the common embankment along Qinghai-Tibet Railway in permafrost regions

the embankment deformation and the change of ground temperature under these embankment are analyzed. It is found that the embankment deformation are of behavior of settlement and closely related with the change of ground temperature under these embankment. After 2-3 freezing-thawing circles

the deformation are tending towards stability in the duct-ventilated embankment

the crushed rocks embankment

the embankment of crushed rock slope protection and the thermal-insulation treatment embankment; but the settlement of common embankment is not stable yet. Meanwhile

the deformation difference of the right-and-left shoulder of embankment is still existent and changed with different embankment types. Based on above-mentioned analysis

we also can obtain a revelation that the compressive deformation of warm frozen soil due to rise of ground temperature under embankment may cause bigger settlement of embankment

maybe it will be one of main reason to result in embankment failure in permafrost regions with warm and high ice content; we should pay much attention to it.
