TECHNICHE ADOTTATE PER LA COSTRUZIONE SOTTO LA CITTA DI SALERNO DELLA GALLERIA FERROVIARIA "SANTA LUCIA" DI KM. 10,265 PER LA DIRETTISSIMA SALERNO-NAPOLI

Problems encountered during the construction of the St. Lucia tunnel under the city of Salerno between the 0 and 1000 m marks are described. The tunnel passes under the city with an 85.3 m2 section of the excavation, the minimum distance between the tunnel roof and the foundations of the buildings above it being 7.5 m and the maximum distance being 25 m. In addition, there is a partially covered brook between the 350 and 1000 m mark in the zone above the tunnel. After a consideration of geohydrological and geotechnical conditions of the zone, the technical solutions adopted and the phenomena observed are described. Such techniques as the driving of root piles, subfoundations, freezing, chemical injections, etc. are elucidated. Many diagrams and photographs illustrate the paper.
