At present experts of «Base and Foundation» department of St. Petersburg Transport University do research work and design projects for transport infrastructure objects. Numerical calculation of subsoil in northern ports of Sabbeta and Tanalau settlements in Russian Arctic region is one of these successfully fulfilled projects. Specific features of these ports are the following: to construct building foundations and road embankments on permafrost soils, to predict functioning of compound sea berths and river piers when super heavy arctic vessels transport liquefied gas along the Northern sea route. Numerical calculation allowed defining soil thawing zone under the northern ports’ structures. Experience of experts permitted to choose the best solutions to preserve natural soil structure and exclude uneven deformations, which destroy objects and complicate roads functioning in permafrost zone.
