摘要
The jointed track design with timber sleepers is conventional for the trunk lines of Ukraine with radius less than 350 m. Such design is not rational. The fact that the big number of the rail joints is the reason why the dynamic forces of interaction in both vertical and horizontal plane are increasing and, consequentially, development of residual deformation on the rail as well. The transient loads are the main reason why the resources of the rail and vehicle structural members work are decreasing. Considering the continuous welded rail design in the curves of short radius, especially the one which is less than 350 m, need engineer estimate. During the work performed some theoretical study on the possibility to arrange the continuous welded rail of temperature-stress type on the ferroconcrete sleepers in the curves of short radius, especially 300-350 m. Provided the results of the calculations of factors of longitudinal and transverse stability of the railway track with taking into consideration the distinctive features of driving the train. Made the respective conclusions concerning the possibility to operate the continuous welded rail of temperature-stress type in the curves of the radius 300-350 m.
