The invention discloses a static and dynamic load control system and method for a ground anchor type space cable three-tower suspension bridge. The system comprises the ground anchor type space cable three-tower suspension bridge and a static and dynamic load control unit arranged on the ground anchor type space cable three-tower suspension bridge. The ground anchor type space cable three-tower suspension bridge comprises a main beam, a middle tower, side towers, transition piers, anchors and space linear main cables, wherein the middle tower, the side towers, the transition piers and the anchors are arranged on the main beam, and the space linear main cables are arranged on the anchors and the main beam. The static and dynamic load control unit comprises a damping and energy-consuming longitudinal limiting support arranged between the middle tower and the transverse connecting box on the main beam in the longitudinal bridge direction, damping and energy-consuming wind-resistant supports arranged between the middle tower and the steel box beam on the main beam and between the side towers and the steel box beam on the main beam in the transverse bridge direction, and vertical supports arranged at the joints of the transition piers and the steel box beam on the main beam. The flutter wind-resistant stability of the full bridge is improved through the space linear main cable; the longitudinal energy dissipation capacity of the bridge is improved through the damping and energy dissipation longitudinal limiting supports; the transverse shock absorption capacity of the bridge is improved through the shock absorption and energy dissipation wind-resistant supports.
