DOI: 10.1002/ppp.70003
Abstract: In permafrost regions, separated crushed‐rock embankments (SCREs) are crucial for constructing high‐grade highways, as they significantly mitigate the thermal impact on the underlying permafrost. Through numerical simulations, the research examines the influence of embankment spacing,… read more here.
