Abstract:

Trial designs of three different cable-stayed bridges, namely traditional fully self-anchored cable- stayed bridge (CSB), partially earth-anchored cable-stayed bridge (PEACSB) and cable-stayed- suspension bridge (CSSB), are carried out based on the same design criterion with the mid-span of 1400m. Results show that all three structures are feasible. Based on numerical calculation, effects of several structural parameters on static performance are presented. The three structures are compared regarding mechanical performance and cost. Results show that PEACSB and CSSB are favourable. As an application, in the design competition of the Second Humen Bridge, PEACSB and CSSB are applied to two navigation channels, respectively. Main ideas and outlines of the two schemes are presented. Finally, the prospect of the research on structural system of super 1000m cable-stayed bridges is discussed.
