The application discloses a vertical curve bridge structure of asymmetric longitudinal slope and a design method and device thereof, and relates to the technical field of bridge design.The design method comprises the following steps: taking any one end point of a tie rod vertical curve as a rotation original point, rotating the other end point by a set angle until the line connecting the two end points is horizontal; determining an arch rib and all hangers according to the rotated tie rod vertical curve to form a whole vertical curve bridge structure; taking any one end point of the tie rod vertical curve as the rotation original point, inversely rotating the whole vertical curve bridge structure by a set angle until the two end points of the tie rod vertical curve respectively coincide with two supporting points. The application further provides a design device for implementing the above design method and a bridge designed by the design method. By rotating the tie rod vertical curve with any one end point as the rotation original point until the symmetry axis of the tie rod vertical curve coincides with the plumb line, the design of the hangers and the arch rib can be performed in a symmetrical design manner, and the design and manufacturing difficulty is greatly simplified.
