Abstract In response to the design requirements of the landscape bridge tower of long span cable-stayed bridge, according to the mathematical equation of egg-shaped curve, a long span cable-stayed bridge with egg-shaped arch tower was proposed.Compared with the traditional cable-stayed bridge with the parabolic tower, the 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, static analysis and modal analysis are carried out. The analysis shows that the cable-stayed bridge with egg-shaped arch tower has good spatial structural stiffness.
