In response to the design requirements of the landscape bridge tower of a long-span cable-stayed bridge, according to the mathematical equation of an egg-shaped curve, a long-span cable-stayed bridge with an egg-shaped arch tower was proposed. Compared with the traditional cable-stayed bridge with the parabolic tower, the two legs of the arch tower are closer, the foundation size is reduced, the tower top is wider, and the three-dimensional spatial stayed-cables are arranged dispersedly, so the bridge landscape effect is better. Combined with practical engineering, the engineering parameters are designed, Midas finite-element analysis model is established, and static analysis and modal analysis are carried out. The analysis shows that the cable-stayed bridge with an egg-shaped arch tower has good spatial structural stiffness.
