Abstract: The crushed-rock embankment and duct-ventilated embankment have been used as effective cooling measures to protect permafrost underlying the Qinghai-Tibet Railway from thawing in China. These two cooling techniques are not ...

Abstract: Frost heave is the primary cause of frost damage in cold regions. For frost-susceptible soils, water migration induced by a temperature gradient is a key factor in determining the frost heave of the soils with a water ...

Abstract: In this study, a series of laboratory investigations were performed to examine the heat transfer performance of a two-phase closed thermosyphon (TPCT) with different inclination angles under low-temperature conditions. A ...
