摘要Aiming at the city wide deck cable-stayed bridge, a double separated deck and four-cable-stayed bridge with univalent hyperboloid single column bridge tower was proposed.The bridge deck with double separated steel box girder replaces the bridge deck wide steel box girder, the univalent hyperboloid single column bridge tower replaces the double column bridge tower, and the four-cable-stayed bridge replaces the double cable-stayed bridge.The univalent hyperboloid single column tower bridge has a thick bottom, which can ensure the bearing capacity of the single column tower structure; the waist of the bridge tower is small and the driver's vision is wide; the wider top of the bridge tower can facilitate the scattered anchoring of stay cables.Combined with the 200 m+420 m+200 m double separated deck and four-cable-stayed bridge with the univalent hyperboloid single column tower, the engineering parameters are designed, the Midas finite element analysis model is established, the static analysis and dynamic modal analysis are carried out, and the structural rationality of double separated deck and four-cable stayed bridge with the univalent hyperboloid single column tower is verified.
