Abstract

:This article examines the technical and practical aspects of using geosynthetic materials to reinforce railway subgrades constructed on weak soils. In modern railway infrastructure, ensuring subgrade stability and safe train operation requires addressing key challenges associated with weak soils, such as low bearing capacity, high compressibility, excessive settlement, and water saturation. The study analyzes the role of various geosynthetics—including geotextiles, geogrids, geocells, geocomposite drainage layers, and geomembranes—in load distribution, preventing ballast–soil mixing, managing water flow, and reducing deformation. Experimental studies and field applications demonstrate that the use of geosynthetic layers can increase subgrade stability by up to 40%, reduce settlements by 35–50%, and significantly enhance the operational efficiency and durability of railway tracks.
