Calculation of slope stability against erosion deformations

Abstract

The paper considers the problems of erosion deformations occurrence for non-flooded slopes of railroad earth bed, where the main causes of scour are atmospheric precipitation or longitudinal currents along the bottom of the slope. The local stability of slopes is calculated taking into account the estimated velocity of water flow on the slope when water moves along the slope. Climatic conditions and soil characteristics on the Bukhara-Misken line were used for calculations. If local stability of slopes is not ensured, measures for slope stabilization are appointed. The technology of reinforcement of embankment slopes with geosynthetic materials with backfilling with a layer of vegetative soil and grass sowing is considered. The stability coefficient on the displacement surface is calculated taking into account the application of the selected reinforcement design. The stability coefficient on the displacement surface taking into account geomat reinforcement increased 3 times and exceeded the permissible minimum value.
