In order to study the longitudinal force and deformation law of CWR of ballastless track on the continuous rigid bridge of the metro, based on the principle of beam-plate-rail interaction, a spatial fine coupling model of CWR of the integral track bed type ballastless track on the continuous rigid bridge of the metro with 100m roadbed + 4×40m continuous rigid bridge + 4×40m continuous rigid bridge + 100m subgrade was established, and under stretching, bending, braking and broken rail conditions,the displacementtrack and longitudinal force of track structure and bridge were calculated, and the static characteristics of the track structure were compared and analyzed. This paper provides a reference for the design of CWR track structure on continuous rigid bridge of metro. The results show that when the midpoint of the double-line train load coincides with the end of the middle beam, the vertical load of the train is the most unfavorable working condition, and the force of the rail and the displacement of the rail and bridge are the largest, and the values are 70.3kN, 0.6mm and 0.8mm, respectively. When the tail of the double-line brake load train is located at the end of the beams on both sides, the most unfavorable working condition of the train braking load, at this time, the longitudinal force of the rail and the longitudinal displacement of the rail and the bridge are the largest, and the values are 107.8kN, 1.6mm and 1.7mm, respectively. Under telescopic force, each end bridge joint is a weak part, and attention should be paid to the structure at the end bridge joint of the beam in the usual maintenance to prevent rail breakage due to excessive expansion force; When the rail is broken under cooling conditions, the longitudinal force and longitudinal displacement of the broken rail are abruptly changed at the fracture, which seriously affects the safety of the line.
