Product Details
The depth of the main girder is less than half that of a beam bridge with the same span. The height of the pylon is generally 1/12 to 1/8 of the main span, significantly lower than that of a conventional cable-stayed bridge (which is typically 1/7 to 1/4). It combines the rigidity of the main girder with the flexibility of the stay cables, resulting in a structure that is grand yet visually integrated.
Production Applications
Compared to conventional cable-stayed bridges, the extradosed bridge features shorter pylons and cables, leading to lower construction difficulty and cost. Additionally, it offers greater structural stiffness and stable mechanical performance. Its reduced foundation requirements make it a versatile and cost-effective solution for a wider range of applications.
