Control over transverse shifts of rail sleeper lattice which impact on deformation of ballast layer

摘要

The main problem in article is influence of warping continuous welded railway track and transverse shifts of rail-sleeper lattice. Transverse shifts of rail-sleeper lattice lead to defects of railway track geometry, caused by lateral movement of ballast. It leads to ballast layers stability loss and it has negative influence on safety of railway traffic. Incessant control of thermally stressed state of continuous welded railway track is necessary, especially warping control of continuous welded railway track, because it is important factor to stability of ballast layer and stability of railway track. Baliza is a device providing control of transverse stability of railway track, which influence on the deformation of ballast layer. Baliza allows to define speed and acceleration of longitudinal thermal mechanical stress variation. In article, one can see measurement and parameter calculation method. This method is based on the measurement and comparison of existing thermal mechanical stresses and calculated mechanical stresses in each point of the rail strings. The article describes a method to control warping continuous welded railway track and transverse shifts of the rail-sleeper lattice that directly impact stability of the ballast layer.
