The invention discloses a multiphase transversal arrangement circular laying construction method, which adopts a major engineering barge as a submarine cable laying ship, and adopts transversal arrangement of submarine cables, back-twist of a pi-shaped back-twist rack and transverse pull of heave away anchors of the barge, and comprises the concrete steps of construction preparation, top end landing construction, middle sea segment laying construction, tail end landing construction, circularly laying construction and submarine cable protection. The method has the advantages that the effective operation area is large, the adverse environmental impact can be effectively resisted, the laying and inclination adjustment efficiency is improved, measurement and control can be accurately performed, the routing deviation is avoided, the degree of automation is high, and the construction efficiency is high.
