Resumen
La realización de paso bajo obras lineales implica afecciones importantes a las redes de transporte. Para minimizarlas se desarrollaron diversas
técnicas mediante pilotes, pantallas, excavaciones manuales, etc. De esta forma, sobre todo en el caso ferroviario, se conseguía que el corte
completo de tráfico se redujera a unas pocas horas, aunque con importantes limitaciones de velocidad durante la ejecución de las obras preparatorias. Para minimizar estas afecciones, en los años 80 se introdujeron técnicas basadas en el empuje oleodinámico de la estructura bajo el
ferrocarril, que permitían la colocación de la estructura en su posición definitiva manteniendo en todo momento el servicio. En este artículo se presenta un conjunto de novedades introducidas en estos sistemas, los cuales permiten optimizar aún más, técnica y económicamente, estos sistemas.

Abstract
The construction of underpasses below railways and roads has a serious impact on transport networks. In order to minimize the impact of these
works, techniques have been developed using diverse elements such as sheet piling, retaining walls, manual excavations, etc. In this way, and
particularly in the case of rail underpasses, traffic stoppages may be reduced to just a few hours, though speed restrictions have to be set in
place during the preparatory work. In an attempt to reduce these disruptions, techniques were introduced in the 80's which were based on the
jacking of the structure below the railway and which allowed the structure to be set in place while keeping the railway open to traffic at all times.
