Two-phase closed thermosyphon-induced frost jacking of piles

Two-phase closed thermosyphon (TPCT) is widely used to cool foundation soil and improve the stability of structures in cold regions. However, along with the cooling of soil surrounding a TPCT, frost heaving of soil can occur, which might pull the structures out, but this phenomenon has rarely been reported. In this paper, based on field observations along the

It should be noted that a site having all three ingredients necessary for frost heave does not guarantee that frost heave will occur. Similarly, a site that lacks one of the ingredients is not necessarily immune from frost heave. There are only degrees of susceptibility. What do building codes say about frost heave? Remarkably little.
