The invention provides a safety structure of a post-built light roadbed above a subway and a construction method thereof, and the safety structure comprises auxiliary assemblies which are perpendicular to the ground, and the lower ends of the auxiliary assemblies extend below the bottom of a subway tunnel structure and are distributed at the two sides of the subway tunnel at equal intervals; the protection assembly is parallel to the ground and located above a lining structure of the subway tunnel; the supporting assembly is used for connecting the protection assembly and the auxiliary assembly; the protection assembly is lower than the upper end of the auxiliary assembly. By the adoption of the protection assembly, the settlement effect of the post-built roadbed is avoided, the borne load is transmitted to the lower end and the periphery of the subway tunnel through the concrete vertical columns and the concrete inclined columns in the protection assembly, the load on the upper portion is reduced, the safety
