This invention relates to the field of landscape bridge technology, and discloses a V-shaped pier-truss cable-stayed composite bridge structure and its construction method. The V-shaped pier-truss cable-stayed composite bridge structure includes piers, main beams, bridge towers, and cables. The piers include V-shaped main piers. The load of the main beam is transferred to the truss structure via the cables through the cable-stayed towers. The truss structure then transfers the force to the V-shaped main piers. The V-shaped piers provide support and constraint to the main beams through their rigid frame action. Thus, through the interconnection and support between the rigid frame structure, truss structure, and cable-stayed structure, the overall stiffness of the combined bridge structure is greater than the sum of the stiffnesses of the individual structures. This optimizes the stress on the cable-stayed towers and the overall bridge structure, allowing the V-shaped pier-truss cable-stayed composite bridge structure to reduce the tower height compared to existing cable-stayed bridges for the same span, thereby meeting the building height requirements of urban planning or enabling it to be suitable for larger bridge spans.
