An application of the Boundary Element Indirect Method is presented as a way to obtain design values of the “raking” of tunnels with rectangular cross section, subjected to earthquake excitation. Focus is on cut-and-cover type of tunnels, i.e. structure that are close to the ground surface. The features of the computer code UNDERGROUND are summarized. Applications to practical design cases show the importance of lateral diaphragms in the reduction of the design raking.

Abstract
An application of the Boundary Element Indirect Method is presented as a way to obtain design values of the “raking” of tunnels with rectangular cross section, subjected to earthquake excitation. Focus is on cut-and-cover type of tunnels, i.e. structure that are close to the ground surface. The features of the computer code UNDERGROUND are summarized. Applications to practical design cases show the importance of lateral diaphragms in the reduction of the design raking.File in questo prodotto:
