    • Soil Moisture Variations in Frozen Ground Subjected to Hydronic Heating 

      Sveen, Svein Erik; Nguyen, Hung Thanh; Sørensen, Bjørn Reidar (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-10)
      Full-scale thawing experiments, performed on three types of homogenous, initially frozen soils, were carried out during late winter 2011 and repeated in 2012. An auxiliary heat source (hydronic heating) was employed to initiate and expedite the thawing process. The corresponding phase change, soil temperature increase, and variations in bound and unbound water content were monitored during the ...

    • Thaw Penetration in Frozen Ground Subjected to Hydronic Heating 

      Sveen, Svein Erik; Nguyen, Hung Thanh; Sørensen, Bjørn Reidar (Peer reviewed; Journal article; Tidsskriftsartikkel, 2016-09-22)
      To facilitate excavation and foundation work in seasonally freezing or permafrost regions, the frozen soil must be thawed, either by natural (solar) thawing, or by artificial thawing where an auxiliary heat source is utilized to accelerate the process. In this paper, the process of rapid thawing of frozen ground subject to hydronic heating is studied. In particular, the performance characteristics ...
