Bondarenko I. Upgrading estimation of capacity of railway due to the improvement of computation descriptions of subrail foundation

On the basis of model of construction of railway at the external action of rolling stock for research of deformative processes of subrail basis, conducted experiments and theoretical researches, executed complex estimation of influencing of different factors on the size of the module of resiliency of track in the vertical plane, developed method of determination of the marked size for the engineering computations of track. The offered complex method settles to put together computations of path on durability and on stabilization of earthen linen; to estimate deformativity paths, at the decision of question about the increase of rate of movement and carrying capacity of trains, allows to take into account reliability indexes of path, to decide a question about the change of operating terms complex and it is differentiated; to promote influencing and efficiency of application of elements of track, to determine the measures on stabilization of deformativity track UIC60. The got theoretical and practical results are used for implementation of research works on the task of headquarters of travel economy of Ukrainian Railway Department (Ukrzaliznytsja).
