SELECTION OF A SITE SUITABLE FOR THE CONSTRUCTION OF AN UNDERGROUND LABORATORY IN A CLAY FORMATION
This report summarizes the results of research conducted by ENEA in Italian territory in order to identify a site suitable for the construction of an underground laboratory in a clay formation. Mining tunnels, abandoned civilian (public) tunnels, natural and artificial escarpments were considered before the Pasquasia mine in Sicily was selected. The local series consists of highly compacted Pliocene clays, frequently with the granulometry of silt. The entire series is traversed by a lift shaft which connects the outside of the mine with the potash salt work-faces. The area considered for the laboratory was at 100 m deep. Plans for the construction of the laboratory and its size are described. Experiments to study the thermal, hydrological, mechanical and thermomechanical behaviour of the clay are planned. Data will be acquired on temperature variation, pressure of interstitial fluid, total pressure and deformation caused by heating deep within the clay. Data concerning the mechanical behaviour of the clay series will be recorded before, during and after excavation of the tunnels, and studies made on their agreement with theoretical data.
