What is Tunnel Lining Thickness Impact Study about?

The document discusses a study assessing the reduced thickness of tunnel linings to ensure stability in soft ground tunnels. The objectives are to determine the deformation of the tunnel and soil-tunnel reaction with reduced lining thickness. A 3D model was created of a 46m tunnel through soft soil layers. The lining thickness was varied from 0.275m to 0.1375m. Results showed increased ground settlement and crown reaction with reduced thickness. Thinner linings experienced greater deformation indicating red
