ARTICLE ANNOTATION

quote
This article analyzes current challenges in the design and operation of transport structures in seismically active regions with complex climatic conditions. The study examines the engineering-geological and hydrogeological characteristics of saline and highly saturated soils, the patterns of their behavior under seismic воздействия, and the impact of these factors on the strength and stability of transport structure foundations. At present, in many regions of the country, including desert and semi-desert zones, highways, bridges, overpasses, and other transport facilities are constructed on saline soils. Long-term saturation, rising groundwater levels, and salt leaching significantly alter the physical and mechanical properties of such soils, increasing the risk of differential settlements and deformations under seismic loading. The paper substantiates that seismic vibrations in saline soils intensify suffosion processes, disrupt soil structure, and change filtration characteristics, thereby negatively affecting the operational reliability of transport infrastructure. In addition, the study addresses the intensification of corrosion processes in foundations and underground structures under the influence of aggressive groundwater and evaluates their impact on service life and structural safety.
