Abstract: | Tunnels are increasingly being excavated in soft ground conditions when services are required in urban environments, and it
is now common to have tunnels crossing at various elevations. As the tunnel excavations are undertaken at different levels,
there will be an interaction which can have a significant influence on stress distributions and consequently deformations
within the tunnels and surface settlement. As multi-layer tunnelling is a three dimensional phenomenon in nature, 3D numerical
solutions must be utilized for perpendicularly crossing tunnels at various levels. This paper reports the investigations into
the changes in stress distribution, deformations and surface settlements which may be expected when the twin Tohid Tunnels
pass beneath the Line 4 metro tunnel in Tehran. |
