| 英文摘要 | High-grade highways designed for large traffic volumes need wider embankments than railways and low-grade highways. In permafrost regions, a wide and dark-colored asphalt pavement surface of high-grade highways may destabilize underlying permafrost if the embankment is insufficiently cooled, especially under a warming climate. However, the embankments with single commonly cooling technique, e.g. two-phase closed thermosyphon (TPCT) embankment and crushed-rock embankment cannot satisfy the cooling requirement of high-grade highways because of their limited cooling capacities. Here, we use a full-scale field experiment of a separated high-grade highway with double lanes each direction at Beiluhe in the Qinghai-Tibet Plateau to investigate the thermal characteristics of a novel composite embankment combined with L-shaped TPCTs, crushed-rock revetments and insulation, as well as an unprotected embankment (as a control). Experimental results indicate that the composite embankment can effectively cool the underlying permafrost and raise the permafrost table under the separated high-grade highway with a wide and dark-colored pavement, whereas the unprotected embankment cannot. This composite embankment should be considered for application to separated high-grade highways with double lanes each direction in permafrost regions, such as the planned Qinghai-Tibet Expressway.
