A series of examples is presented on the use of the finite element method for the stress analysis of tunnels. Some of them intend to provide an interpretation of the behaviour of the tunnel observed during construction. Other examples try to illustrate some effects influencing the behaviour of underground openings, like e.g. the squeezing of rocks or the change of pore pressure during excavation. The discussion is confined to static problems and to continuous rock/soil masses. In all examples a linearly elastic behaviour of the support is assumed while, depending on the problem, different linear, non linear and time dependent constitutive laws are adopted for the soil/rock mass.

Abstract
A series of examples is presented on the use of the finite element method for the stress analysis of tunnels. Some of them intend to provide an interpretation of the behaviour of the tunnel observed during construction. Other examples try to illustrate some effects influencing the behaviour of underground openings, like e.g. the squeezing of rocks or the change of pore pressure during excavation. The discussion is confined to static problems and to continuous rock/soil masses. In all examples a linearly elastic behaviour of the support is assumed while, depending on the problem, different linear, non linear and time dependent constitutive laws are adopted for the soil/rock mass.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
