Ribbon-shaped single-tower cable-strayed-steel structure combined bridge and construction process thereof
The invention discloses a ribbon-shaped single-tower cable-strayed-steel structure combined bridge and a construction process thereof. The combined bridge comprises a lower supporting structure, a main beam, an arch-shaped main tower which is arranged on the main beam and gradually backwards inclined from bottom to top, and two ribbon-shaped supporting structures which are positioned at the rear side of the main tower; the two ribbon-shaped supporting structures are both integrally fixedly connected with the main beam; the two-ribbon-shaped supporting structures and the main beam are lengthways arranged along the bridge direction; a plurality of cable-strayed ropes are arranged between the main tower and the main beam; each ribbon-shaped supporting structure is divided into a lower ribbon-shaped supporting structure and an upper ribbon-shaped connecting structure through the main beam. The construction process of the combined bridge comprises the steps of 1, constructing the lower supporting structure; 2, constructing the lower ribbon-shaped supporting structure; 3, constructing the main beam; 4, constructing the main tower and the upper ribbon-shaped connecting structure. The combined bridge is reasonable in structural design, convenient to construct, outstanding in mechanical performance and a good in use effect; a non-back cable-stayed bridge and a continuous rigid structural bridge are effectively combined, and the advantages of the two bridges are brought into full play.
