In this paper, in order to improve the seismic performance of frame type double deck overpass bridge under seismic action, the most reasonable restraint system of frame double-deck overpass is studied. Based on the typical frame-type double-deck continuous overpass-hushen bridge, the finite element analysis model of the solid bridge is established. Then, from six different directions, eight different constraint combinations are established. Finally, through the analysis of the bridge direction control point of the internal force, displacement and other parameters, research and contrast the frame double-deck overpass under different constraints of the seismic response. The results show that the combination of rubber bearing, steel wire rope and concrete block can effectively limit the relative displacement between piers and beams, and reduce the internal force response of Piers and residual deformation of supports.
