Core plate type steel-concrete combined arch rib structure and construction method and application thereof

The invention discloses a core plate type steel-concrete combined arch rib structure and a construction method and application thereof, and belongs to the technical field of arch bridge design. Through corresponding arrangement of an arch-shaped steel truss and a reinforced concrete core plate in the middle of the steel truss, a reinforced concrete material of an arch rib can be located on a neutral axis of the arch rib or near the neutral axis of the arch rib, therefore, the supporting stability of the arch rib structure is effectively improved, and cracking of the concrete structure is reduced. The core plate type steel-concrete combined arch rib structure is simple in structure and easy and convenient to set, the tensile stress of reinforced concrete in the steel-concrete combined arch rib can be effectively eliminated or reduced, the reinforced concrete can be protectively utilized, the reliability and stability of arch rib structure setting are fully guaranteed, the utilization of steel and reinforced co
