The invention discloses a method for improving interface connection performance between a filling layer and a track plate. The method comprises the following steps: preparing isolation cloth which is consistent with a bottom plate of the track plate in size and can permeate and adsorb cement paste on two sides; after track plate concrete is vibrated and flattened, isolation cloth is flatly laid at the bottom of the track plate, so that a slurry-rich layer on the surface of the track plate concrete permeates into the isolation cloth, and a strong-bonding compact cement slurry layer is formed by the slurry-rich layer and the isolation cloth; the method comprises the following steps: paving a track plate with isolation cloth adhered to the bottom, performing fine adjustment and edge sealing, then pouring self-compacting concrete, in the pouring process of the self-compacting concrete, enabling internal floating slurry to permeate into the isolation cloth adhered to the bottom surface of the ...
