Geological Conceptual Model for Underground Works Design,ptual models have to be defined: the geological model, obtaining a representation of the spatial distribution of materials, tectonic structures, geomorphological and hydrogeological data concerning the area of influence of the underground work; the geological-technical model, representing the lithot

In this chapter is also described an applicative example: the decision aids for tunnelling (DAT). This programme can simulate the realization of a tunnel starting from a geological

The different methods described are: the Rabcewicz method; the method of hyperstatic reactions; some simplified methods able to assess the loads acting on the lining (vertical loads, horizontal load, inclined loads, loads in case of tunnel under groundwater table); the different methods that can

The following main surveys, measurements and controls are described: geomechanical surveys of the excavation face or walls; measurements of convergences; measures of rock deformations (face extrusion and radial deformations); measures and controls on linings (assessment of strain with ‘strain

Nonetheless, once reports of other phenomena such as St. Elmo’s fire had been eliminated, the remaining descriptions were remarkably consistent. Furthermore, nearly all who contacted me were keen to have an explanation of what they had se
