description The invention discloses a device for improving stress distribution of a swivel cable-stayed bridge, and a mounting method thereof. The device comprises a steel truss, embedded steel bar anchor rods used for being connected with a lower bridge tower of the cable-stayed bridge are arranged on two sides of the steel truss, a steel plate is fixed on the steel truss, and a force application mechanism is arranged on the upper surface of the steel plate. According to the steel truss, the transverse connection of the bridge tower can be effectively improved, the hogging moment bearing capacity of thebridge tower is improved, and the stability of swivel construction is improved; the force application mechanism provides elastic support capable of being automatically adjusted for the main beam so asto improve stress distribution of a tower pier beam consolidation area and reduce stress concentration; and the force application mechanism can also adjust the unbalanced moment difference generatedby a bridge rotating body i
