Viaducto sobre el Polcevera, en Génova, Italia

摘要

Recientemente ha sido terminado y puesto en servicio el viaducto sobre el Polcevera, en Genova, para la autopista Savona-Génova, algunas de cuyas particulares condiciones de adaptación han obligado a resolver una serie de problemas que se indican en el artículo. Se trata de una construcción de dimensiones notables que, junto con algunas otras de importancia parecida, ya ejecutadas o bien en construcción, contribuye a demostrar la posibilidad de realizar obras de luces cada vez mayores, sin más que seguir admitiendo la técnica y la tecnología del hormigón armado y pretensado, debidamente aplicadas.↓The construction of this important project has only been possible thanks to the progress achieved in prestressed concrete technology. The work involved considerable difficulties due to the size of the project and the location, which made it necessary to complete this bridge simultaneously with other essential public facilities. Suitable solutions to this problem have been found, which made it feasible to bridge over spans, which previously were regarded as prohibitive. These solutions were also consistent with an optimum reduction of the area on which the bridge is supported. The structure has been designed to show maximum efficiency under the apphed loads which will act on it, and this has saved a considerable amount of material. The Polcevera viaduct, at Geneva, of 1,102.45 ms length has become an important connecting point in the local system of communications, and links two motor roads by means of an elevated roadway.
