The concept of floating submerged tunnels becomes increasingly attractive idea to cross the straits. The structural solution in these bridges includes buoyancy force on tunnel body plus tension in mooring tethers. This paper investigates the effect of submergence on the dynamic response of submerged floating tunnels due to moving load. The inertial effect of the fluid on the submerged structure...
This paper proposes an analytical method based on drained solutions of cavity expansion and contraction in a unified clay sand model to investigate tunnel–soil–pile interactions. Cavity analyses are used evaluate the effects pile installation ground stresses determine end-bearing capacity distribution shaft friction. methods were adopted replicate tunnel convergence–confinement response using s...
micro gravity data was collected in a crowded street in tehran where a subway terrain tunnel is to be excavated. the data is corrected for the gravity effects of the surrounding densely built up area with diverse buildings and the bouguer gravity anomalies are computed. the residual gravity anomalies are prepared by removing a trend surface. upward continuation is used to remove the gravity eff...
