Abstract The present work contains the results of studies devoted to determining the effect of the stiffness of bridge piers in the plane of the bridge structures on the longitudinal forces in the rails welded rails on the bridge. The calculations used the finite element method. As a design scheme of the receiving system “bridge-jointlesstrack”, and spans were assumed to be riding on the ballast, so that the connection between the rail and the rail base were made of elastic-plastic. As a result of the analysis revealed the dependence of the longitudinal forces in the rails welded rails on the bridge of stiffness parameters bridge supports. In particular, we studied the influence of the stiffness of soil at the base of the supports efforts in the rails of the deck with welded through.
