Self-anchored concrete suspension ribbon bridge with flat arch ribs on bridge surface
The invention discloses a self-anchored concrete suspension ribbon bridge with flat arch ribs on a bridge surface. The flat arch ribs are arranged on the bridge surface of the self-anchored concrete suspension ribbon bridge, and connected with the bridge surface and stand columns through tie bars. The flat arch ribs protruding upwards are arranged, so that the neutral line of the cross section of the self-anchored bridge-surface structure rises, and the height of the gravity center of the bridge-surface structure is raised; the flat arch ribs bear part of dead loads of the bridge, so that the axial load stress generated by lower chords of the suspension ribbon bridge on a bridge panel is reduced; besides, the linetype of the bridge surface and the running comfort of vehicles are not influenced. The self-anchored concrete suspension ribbon bridge disclosed by the invention is scientific in design and simple in structure, and can promote the suspension ribbon bridges to be applied in high-grade highways.
