The stress distribution of the three-span continuous bridge deck with steel-polyurethane sandwich structure is studied. The changes of parameters for the sandwich bridge deck have a great effect on the buckling modes and the critical loads. The closer to the center of the compression section, the greater the longitudinal stress on steel faceplate, but it is smaller at the bottom of the stiffening ribs. The longitudinal stresses on the steel faceplate and at the bottom of the longitudinal stiffeners are unevenly transverse distributed.
