Railway bridges - different type proposals
Se presenta un conjunto de puentes empujados de hormigon pretensado y de seccion cajon, con luces de 45 m, 60 m y 65 m para realizar viaductos de pocos cientos de metros de largo hasta mas de un kilometro de longitud. Son puentes continuos con frenado recogido en el estribo. Tambien se presenta el cruce del rio Ebro, con 120 m de luz para la linea de alta velocidad Zaragoza-Barcelona-Frontera Francesa. Es un puente de seccion hueca y almas perforadas que a modo de una viga Vierendel constituye la estructura basica que es penetrada por el tren para pasar de una a otra orilla. Un tren dentro de otro tren. Finalmente se presenta la estacion y los viaductos en la estacion de Urbinaga en Bilbao y el puente de tubos que soporta al funicular que sube a Montserrat. (A). English abstract:The article presents a combination of launched prestressed box section bridges with spans of 45 m, 60 m and 65 m forming viaducts from just a few hundred metres up to over a kilometre in length. These are continuous bridges which accommodate braking reactions at the abutments. The article also presents the 120 m span crossing of the River Ebro on the Zaragoza-Barcelona-French border high speed railway line. This is a hollow section bridge with perforated webs in the form of a single Vierendel beam which serves as the basic structure penetrated by the train when crossing the river and much in the manner of a train within another train. The article concludes with a presentation of the station and viaducts at the Urbinaga station in Bilbao and the tube bridge supporting the cable car that climbs up the mountain of Montserrat. (A).
