STUDIES AND SOLUTIONS FOR THE CONSTRUCTION OF A TUNNEL SECTION IN TERRAIN OF CONSIDERABLE HYDROSTATIC PRESSURE
STUDI E SOLUZIONI PER LA COSTRUZIONE DI UNA TRATTA DI GALLERIA IN TERRENI PARTICOLARMENTE SPINGENTI CON PRESSIONI DI TIPO IDROSTATICO
This article describes and illustrates the surveying, excavating and lining of a 1 km stretch of tunnel at Santomarco on the Paola-Cosenze railway line, Italy. The tunnel was drilled through clayey-marl rock formation and extreme hydrostatic pressure was encountered, due to thrust from the mountain. Separate sections in the article deal with: the geology of the mountain area; geomechanical considerations; laboratory and in situ tests; evaluation of the pressures acting on the lining; definition of the geomechanical parameters affecting static design and the forecasting of the loads acting on the lining; and the construction method adopted, consisting of closed shield drilling, the placing of prefabricated reinforced concrete lining shells, and the injection of a strengthening ring of concrete. /TRRL/
