Abstract. The steady development of transport infrastructure in permafrost zones necessitates assessing the performance of structures both during construction and operation, taking into account numerous factors and processes. Operational difficulties often arise due to improperly conducted engineering and geological surveys, leading to the failure of individual road structures. In this article, the authors examine the situation related to determining critical deformations of metal culverts used in artificial structures for the construction of an overpass across the Trans-Siberian Railway in the urban-type settlement of Novobureisky. The authors also examine the causes of ongoing deformations. The article also presents an approach to assessing various risk factors during the operation of the overpass embankment. A comparison of data from previous and current surveys revealed differences in the particle size distribution of coarse-grained soils. Specifically, during the initial survey phase, prior to construction, gravel soil was observed throughout. Currently, laboratory testing of soils sampled beneath the embankment has revealed changes in particle size distribution, manifested in a decrease in the sand fraction content. This suggests that gravitational forces and the hydraulic effects of groundwater have washed out the fine fraction, possibly reducing the soil density and bearing capacity. A potential scenario for subgrade deformation during filtration consolidation of the embankment base, with its characteristics remaining unchanged over time, is considered. Options for ensuring the continued operation of the construction project are proposed, including installing a metal-corrugated pipe within the existing embankment or combining existing metal-corrugated pipes into a single shell.
