- cable-stayed bridge description
Asymmetric single pylon hybrid cabled stayed bridge.
34.5m (6 traffic lanes).
183.5m high inverse Y-shaped RC structure. (hollow section with varying dimension from 9m to 4.98m).
Side span is PC box girder and the main span is an orthotropic steel box girder ---A fully welded structure, including the field joints (no bolt connections !!!).
In Taiwan, bridges come in all shapes and sizes. From rickety suspension bridges on hiking trails, to mammoth viaducts and highway bridges constructed with the latest special construction methods. But, the grandest of them all, and perhaps in all of Asia, is the Kao Ping River Bridge (pronounced Gow Ping), a 2,617m bridge on Taiwan's National Freeway No. 1 linking the southern areas of Kaohsiung and Pingtung County.
The Kao Ping River Bridge features the world's second longest single pylon cable-stayed bridge, an asymmetric bridge consisting of a 330m long main span of fully welded steel girder, and a 180m long side span of PC girder. The bridge is highlighted by the 183.5m high pylon tower structure which holds up both of the spans with 28 sets of stay cables, while the remainder of the bridge is comprised of PC Girder. CECI started the design of the Kao Ping River Bridge Project back in 1992, and henceforth completed the supervision of its construction in the year 2000. Accordingly with the site conditions, the bridge is divided into six units and three different types of structures: (1) Unit 1: The 510m cable-stayed bridge, (2) Units 2 to 3: Prestressed concrete structures constructed by the free-cantilever method with typical spans of 80m and 120m, and (3) Units 4 to 6: Prestressed concrete structures constructed by the advancing shoring method with typical spans of 45.5m.
The bridge is built from a small hill along the riverside so the height of the bridge decreases from unit one to unit six, and to match the change in height, the span lengths also decrease from unit one to unit six. Since its completion, the Kao Ping River Bridge has not only fulfilled its purpose of bringing the communities and people of southern Taiwan closer together, but also serves as a major landmark symbolizing the advancement of economic progress in Taiwan. CECI is proud to have contributed to the culmination of such an enormous engineering achievement.
