| Abstract: |
The Tera Viaduct is situated over the Tera River between km points 710+697.500 and 711+342.500 of the north-northeast corridor of the Madrid-Galicia high-speed railway line. It is therefore 645 m long with a span distribution of 60-75-150-75x5-60. Such arrangement, with one large 150 m span, is determined by the crossing of the Tera River, spanned by an arch. The deck is supported in the arch keystone, which enables constant modulation of the spans throughout the whole viaduct, keeping the same deck cross section and using incremental launching as construction method. The metal section arch was installed by rotating the semi-arches. |
