To study the stress and deformation of ballastless track CWR on rigid frame bridge, predicated on the principle of beam-slab-rail interaction, the models of CRTSⅢ slab track and CRTSⅠ bi-block track jointless track on rigid frame bridge are established respectively. The longitudinal forces and displacements of each structure under the conditions of expansion, deflection, braking and rail breaking are calculated, and the static characteristics of two kinds of ballastless track structures are compared and analyzed, it provides consultation for the track structural design of CWR on rigid frame bridge. The results show that under temperature load and train load conditions the rail longitudinal force of CRTSI bi-block track CWR on rigid frame bridge is smaller, but the relative displacement of rail and track slab increases significantly, which may lead to potential safety hazards; Under the train braking load condition, the longitudinal stress of the rail and the relative displacement of the rail slab of CRTSⅢ slab track CWR on the rigid frame bridge are smaller; Under the broken track condition, the broken joint value of CRTSI bi-block track CWR on rigid frame bridge exceeds the allowable limit of the specification. CRTSIII slab track is recommended for rigid frame bridge.
