ABSTRACT
Railway ballast is an important component of railway track as it distributes the dynamic load to subgrade. Failure of Ballast layer results excessive deformation and track misa-lignment. This study investigates the behaviour of geocell-reinforced ballasted railway tracks un-der static loading conditions. The railway track was modeled on low-bearing-capacity soil, and a dynamic impact factor was account for the effects of train movement. Numerical analysis was performed using the finite element-based software. The three-dimensional railway track was sim-ulated for a train speed of 200 km/h. The subgrade soil and ballast were represented using the Mohr-Coulomb criterion. A detailed parametric study was conducted to evaluate the influence of variations in geocell stiffness, subgrade stiffness, axle load and angle of friction of ballast. The results demonstrate that incorporating geocells in the railway ballast reduces track settlement and enhances performance.
