Abstract

The article presents the geocryological conditions of the area of the planned bridge crossing over the Lena river - the distribution of average annual temperatures of permafrost, taliks and permafrost-geological processes, and phenomena and the thickness of the active layer. A quantitative analysis of the regularities of the spatial distribution of permafrost characteristics has been carried out. A schematic map of the distribution of taliks has been compiled. The study of geocryological conditions served for the further compilation of a Geocryological map of the bridge over the Lena river in the area of Yakutsk on a scale of 1:5,000.
