The importance of using geosynthetic materials in ensuring anti-erosion stability of railway embankments

Railway embankments are key elements of transport infrastructure whose stability depends on soil, hydrogeological, and climatic factors. Wind and rainfall erosion threaten slope integrity, causing soil loss and potential landslides. This study integrates field experiments and modeling to assess erosion mechanisms and the effectiveness of geosynthetic geomats for slope protection. Tests on the Bukhara-Miskin railway section determined wind and rainfall thresholds for soil displacement and evaluated geomat performance by slope stability, vegetation density, and runoff resistance. Reinforced slopes showed almost no soil washout, with vegetation density of 4000-5500 kg/ha – over 200 % higher than traditional seeding. Geomat use reduced erosion by up to 80 % and improved ecological resilience, offering a reliable, cost-effective, and sustainable solution for long-term railway slope stability.
