According to the structural mechanical characteristics of unit ballastless track and the spatial demand of the bridge with criss-cross beams, geometric optimizations were carried out on the slab track.4 T-type bosses are installed around the slab track instead of circular convex in the middle, which lead the slab to adopt to the bridge with criss-cross beams better. The research indicates that the 4 T-type bosses around the slab can reduce the warping stress and warping distortion effectively and the stress is distributed better. Under the train load, the deformation of the track slab tends to decrease, which lead it to more reasonable stress and deformation state.
