Abstract

Un problema del ferrocarril al paso por las ciudades europeas es el efecto barrera generado, que impide su desarrollo más allá de las vías. Si se salta la barrera lo cierto es que ello se hace sólo en sitios concretos y el efecto psicológico de aislamiento persiste para los habitantes del entorno. Este trabajo presenta de manera sucinta los problemas de concepción, comprobación y vibraciones planteados por la estructura de cubierta de la trinchera ferroviaria de Hendaya, consistente en una losa de hormigón pretensado y luz variable de 20-40 metros, que resuelve el problema de aislamiento entre las dos partes de la ciudad. Su construcción ha sido posible gracias al acuerdo entre la SNCF e inversores privados y está permitiendo la construcción sobre ella de 6 edificios de viviendas y una residencia de turismo, la demolición del antiguo ?Pont-Vieux? y la construcción de un nuevo ?Pont-Vieux?, integrado completamente en la promoción inmobiliaria. An important problem put by the train in its passage by the cities of Europe generally and in France in particular is the effect barrier which builds up, preventing the cities from developing beyond. Even if this barrier is crossed, it is certain that the passage is restricted to concrete places and always acts as psychological barrier for the local residents. This article presents in a brief way the problems of conception, analysis and vibration of the cover structure of the railroad trench of Hendaye. This structure consists of a 20-40 meters span slab of pre-stressed concrete that solves the isolation problem of both parts of the town of Hendaye. Its construction was possible thanks to the agreement of the SNCF (French Railways)and some private investors, and is allowing the investors the construction on top of 6 residential buildings and a holiday residence, with demolition of the ancient “Pont-Vieux” and building of a new “Pont-Vieux”, which is completely integrated into the real-estate development. Special attention is given to the change of transverse cross-section of the slab during construction stages, which originates a redistribution of stresses, and to the long-term equilibrium of horizontal forces.
