Abstract

The invention provides a thermosyphon foundation, a method of calculating cold conductivity enhancement coefficient and a method of cold conductivity enhancement thereof. The cold conductivity enhancement coefficient is obtained by using parameters including freezing index, latent heat of soil thawing, thermal resistance of pre-buried hole without injection of a cold conductivity enhancement medium, thermal resistance of cold conductivity enhancement mass or the like, and by using formulas for calculating the cooling radius of the thermosyphon without injection of a cold conductivity enhancement medium and the cooling radius of the thermosyphon after injection of a cold conductivity enhancement medium. The invention determines whether to proceed with subsequent construction by using the cold conductivity enhancement coefficient, and achieves cold conductivity enhancement for the thermosyphon foundation by using the method of cold conductivity enhancement.
