%X The effects of caisson foundation deformation on wind-induced buffeting response at twin-cantilever construction stage of cable-stayed bridge are studied in this paper. In consideration of foundation deformation, the analytical method of wind-induced buffeting response at twin-cantilever construction stage of cable-stayed bridge, whose caisson foundation of bridge tower is located in soil layer, is established. Taking the Haikou Century Bridge as an example, computational results show that the foundation deformation has notable influence on buffeting displacement response, but little effect on longitudinal buffeting bending moment at the bottom of the tower.
