Thermal influences of road engineering on permafrost underneath different surface condition in the Qinghai-Tibet Plateau

Road engineering produces thermal influences on the permafrost on both sides of the road, but this impact is unclear yet. In this study, the thermal influences of the highway on the permafrost underneath different surfaces conditions were investigated by means of permafrost monitoring in two sites along the Qinghai-Tibet Highway (QTH). The results show that on both sides of the QTH there is a significant thermal influence on the permafrost, but...
