Abstract: Seismic activity on a tunnel damages the tunnel support systems. The extent of the tunnel damage depends on the soil type, the magnitude of the earthquake acceleration, and the tunnel cover depth. Hence, analyzing the ...

Abstract: Complete analytical solutions were developed for horizontal and vertical seismic accelerations considering wave velocities varying with depth as a generalized power-law function. This was done by enforcing the traction-free ...

Abstract: This study evaluated the stability of circular tunnels constructed in anisotropic granular soil in the presence of surcharges on the ground surface and seismic loads. The stability problem was solved using the lower bound ...
