Water and salt migration mechanisms are of great significance for understanding the frost
heave and thaw settlement of saline soils during freeze-thaw (FT). In this study …

Cast-in-place piles are popular foundation forms in permafrost regions. The freezing force at
the pile-soil interface is the main source of bearing capacity, which is quite sensitive to …

In cold regions, passive thermosyphons are often employed in permafrost protection and
artificial ground freezing (AGF) applications. While passive thermosyphons utilize available …

Hybrid thermosyphons have been installed in several permafrost protection applications due
to their ability to operate continuously irrespective of seasonal temperature variations. In …

Compared to conventional ground heat exchangers that require a separate pump or other
mechanical devices to circulate the heat transfer fluid, ground coupled thermosiphons or …

During the construction of the±400 kV direct current power transmission line (DCPTL),
frozen blocks were backfilled into the foundation pits in permafrost regions because of the …

The level of nuclear waste emergency disposal is an important factor restricting the rapid
development of the nuclear energy industry under the trend of global energy revolution. To …

Ground temperature distribution is one of the fundamental problems in the theory of artificial
ground freezing. For the most widely applied freezing scheme, single-circle-piped freezing …

A comprehensive technology is proposed to realize fast and safe rock cross-cut coal
uncovering (RCCCU) based on artificial freezing engineering method. This comprehensive …

Permafrost degradation represents a severe challenge for mining operations in Northern
Canada. The foundations of the infrastructures rely on the steadiness of the permafrost …
