Creep Models for Tunnel Squeezing Analysis by fcetss is a document available to read on EtoBox.
This study investigates ground movement and contact pressure in the Stillwater Tunnel (Utah, USA) using finite element analysis with power law and hyperbolic creep models. The analysis reveals that the power law creep model effectively predicts lining pressure and deformation when considering delay time before lining erection. Results indicate that time-dependent deformations significantly impact the stability and support system design of tunnels in squeezing ground conditions.
