The paper addresses the problem of underground tunnels when subjected to asyn- chronous seismic shaking along the axis in comparison with the synchronous case that is usually considered in the tunnels design. The effect of the asynchronous wave passage along the tunnel has been investigated for the case of the Metro Line 6 of Naples (Italy). A comparison between uniform and non-uniform seismic loading condition is proposed in terms of dynamic increment on lining internal forces and time histories of acceleration in correspondence of such control points and sections of the soil.

Abstract
The paper addresses the problem of underground tunnels when subjected to asyn- chronous seismic shaking along the axis in comparison with the synchronous case that is usually considered in the tunnels design. The effect of the asynchronous wave passage along the tunnel has been investigated for the case of the Metro Line 6 of Naples (Italy). A comparison between uniform and non-uniform seismic loading condition is proposed in terms of dynamic increment on lining internal forces and time histories of acceleration in correspondence of such control points and sections of the soil.File in questo prodotto:
