<p>This paper investigates the development of time-dependent strain in tunnels under squeezing ground conditions. A visco-elastic perfectly plastic (VEPP) model was employed to analyze the time-dependent behavior around circular tunnels subjected to anisotropic stresses. The initial calibration of VEPP parameters was performed through finite element plane strain analysis using field data from Atal tunnel, India. Sensitivity analysis was then conducted to evaluate the key VEPP parameter influencing creep behavior. Subsequently, axisymmetric analysis was performed using the back-calibrated parameters to examine the effects of excavation rate and anisotropic stress ratios (<i>K</i>_<i>o</i>) on strain development, highlighting critical transitions in squeezing zones. The results reveal that, at <i>K</i>_<i>o</i> = 0.5, the radial strain reduced by 53%, whereas at <i>K</i>_<i>o</i> = 1.5, it increased by 81.43% compared to the isotropic stress condition (<i>K</i>_<i>o</i> = 1). The increase in <i>K</i>_<i>o</i> triggered a significant shift in strain levels, transitioning a ground from non-squeezing to squeezing zones. Similarly, the excavation rate was found to play a significant role. Slower excavation rates (0.5 R/day) result in increased strain accumulation due to the prolonged exposure of the surrounding rock to the stresses during excavation and experience creep behavior. This approach aids in identifying critical areas that may require additional support, enhancing the practical applicability of the findings.</p>
