Abstract:
Disclosed in the present invention is an arch structure for an extra-large span steel-UHPC combined truss arch bridge. The arch structure comprises multiple rows of arch structural units arranged in the transverse direction of the bridge, the multiple rows of the arch structural units being symmetrically distributed along the central line in the longitudinal direction of the bridge. The multiple rows of the arch structural units are connected to form a whole by means of a connector in the transverse direction of the bridge, and each arch structural unit comprises a web rod and an upper chord arch rib and lower chord arch rib made of a full UHPC material, and the upper chord arch rib and lower chord arch rib are connected by means of the web rod. The present invention also correspondingly provides a cyclic construction method for the arch structure above for an extra-large span steel-UHPC combined truss arch bridge. The arch structure for an extra-large span steel-UHPC combined truss arch bridge of the present invention has the advantage of being lightweight, and the construction method of the present invention has high construction efficiency and a low construction cost. The present invention provides a practical solution for an arch bridge having an extra-large span of 600 m to 1000 m.
