Description
Urban expansion has intensified the need for underground transportation infrastructure, yet tunneling activities often induces ground settlement and groundwater drawdown. In densely built environments, these processes pose substantial risks to surface and subsurface structures, highlighting the need for advanced computational models to better diagnose and predict ground responses. This study introduces a systematic workflow of developing coupled hydro‑mechanical models that capture non‑linear processes in complex subsurface systems involving geological heterogeneity, sophisticated tunnel geometries, and boundary conditions. The proposed framework integrates detailed stratigraphic characterization, site‑specific hydro‑mechanical properties, and realistic boundary representations within a computationally efficient modelling scheme. Particular attention is given to balancing spatial resolution, numerical stability, and computational cost to ensure both predictive accuracy and practical reliability. The workflow is demonstrated through a case study of the West Link project in Gothenburg, Sweden, where a three‑dimensional high‑resolution coupled model was implemented to simulate tunneling‑induced deformation and pore‑pressure variations. The results confirm the robustness and predictive capability of the approach, providing a foundation for design optimization and advancing the understanding of hydro‑mechanical processes in urban tunneling environments.
