The anti-stripping shield tunnel lining segment comprises a segment body and an assembly part, an assembly hole is pre-formed in the side wall of the segment body, the central axis of the assembly hole is perpendicular to the thickness direction of the segment body, the assembly part comprises a sleeve, a positioning part and an embedding part, the sleeve is connected with the positioning part and embedded into the assembly hole, and the embedding part is connected with the positioning part. The embedding piece is connected with the sleeve through the embedding section of the embedding piece, and the other end, away from the embedding section, of the embedding piece is embedded in a ballast bed of the shield tunnel. The assembly holes are preset in the lining segment, the lining segment and the ballast bed can be fixedly connected by matching with the assembly parts, the ballast bed cannot be stripped off from the lining segment even if water leakage occurs during operation, the problem that the ballast bed i
