Abstract:

For the Mingtan Pumped Storage Project of an installed capacity of 1600 MW, two parallel waterways have been constructed for conveying flows between the upper reservoir and the lower reservoir for power generating and pumping operations. Due to the topographical configuration, two arch bridges, each with a clear span of 70 m, have been selected among six alternatives (1) for supporting the waterway steel conduits to run across the Tousheh Creek. Each of the steel conduits, with an inner diameter of 6.8 m, carries flowing water plus its own weight to bring as heavy as 50 t/m of a live load on the deck slab of the bridge. In order to ensure the stability of the bridge under the enormous heavy load against severe seismic action, the arch is so designed to have parabolic curves in both plan and profile. This paper describes briefly for reference the design approach, assumptions and parameters adopted, and results of analysis of the unique bridges.
