dc.description.abstractIncreasing population and high population density of India has put intense pressure on existing railway track. The are operating at a way more than their capacity and this has strained many rail lines which leads to derailment and other mishaps. This high population density suits High speed railway. To fight with increased traffic with regard to speed and loading, the stresses variation in various components must be known accurately to evaluate useful life of each component for its life assessment. To asses this detailed analysis is necessary to develop methodology for every track component under actual loading condition. In this thesis a comprehensive study on the behavior of ballastless track structure for high speed train under stationary load is carried out. Finite element analysis is used for analysis. Different track systems are considered, and the performance of track components analyzed under stationary wheel load. Deflection and stresses are the parameters which is used to analyze the performance of track system. Parametric investigation is carried out for the variation in material properties to study the effect of behavior the track under the effect of different material. Present investigation revels increase in stiffness of rail pad and modulus of subgrade decreases the deflection in track component while increase in modulus of elasticity of concrete slab and CAM layer shows no change in terms of deflection. It is also seen that with increase in all the parameters the contact stress in the rail decreases. But in concrete slab increase in stiffness of rail pad and modulus of elasticity of concrete slab increases the equivalent stress.en_US
