Sutong Bridge-A cable-stayed bridge with main span of 1088 meters

摘要

The Sutong Bridge is the longest spanning cable-stayed bridge in the world with a main span of 1088 meters. In this paper, the design and construction concepts are briefly presented. Key technologies and innovative achievements are summarized. These focus mainly on pile foundation bearing capacity analysis, river bed scour protection and monitoring, superstructure wind-resistance study, mid-span closure method, as well as long cantilever structure construction control.
