Nuclear engineering dome and construction method thereof

The invention relates to the technical field of nuclear engineering civil engineering modular construction, in particular to a nuclear engineering dome and a construction method thereof. The nuclear engineering dome comprises a single-side spherical steel truss body, the single-side spherical steel truss body comprises a spherical steel plate structure and a truss structure, the truss structure is arranged on the outer arc top wall of the spherical steel plate structure, and first-stage concrete is suitable for being poured into the truss structure; the truss structure divides the outer arc top wall of the spherical steel plate structure into a plurality of compartments; the stiffening rib structures are arranged in the compartments, and the stiffening rib structures are arranged in the annular direction and the radial direction of the spherical steel plate structure correspondingly; one axial end of the anchoring stud is fixedly connected with the spherical steel plate structure; the single-side spherical st
