The invention belongs to the technical field of tunnel construction, and in particular, relates to a tunnel lining construction method, and aims to solve the problems of need of replanning of tunnel lining structures due to incapability of meeting sky train driving conditions by tunnel structures and no way to develop the construction work due to high design difficulty in sky train rail construction in tunnels in the prior art. The tunnel lining construction method comprises the following steps: (S1) the secondary lining preparation work is performed on the basis of finishing the primary lining and inverted arch constriction of tunnels to be constructed; (S2) waterproof plates are paved; and secondary lining reinforcements are bound; (S3) concrete is pumped to side edge walls on the two sides of the tunnels to form secondary lining main body structures; (S4) sky train rails and rail mounting frames are mounted; and (S5) the concrete is pumped to inverted arches of the tunnels. The tunnel lining construction method enables the sky train rails and the tunnel main bodies to form excellent stress wholes, is more stable, safer and more reliable in operation of sky trains, and is simplein structure, high in operability and low in cost.
