Shielding Effect Between Tunnels Subjected to Ground Deformation Due to Adjacent Deep Excavation by the Linear and Non-Linear Pasternak Model
Key Points
The shielding effect mitigates ground deformation in adjacent tunnels during deep excavation, enhancing structural integrity.
Excavation for deep foundations causes measurable deformation in surrounding tunnels, with variations observed across different models.
Analysis using the linear and non-linear pasternak model indicates distinct behaviors in tunnel response to excavation-related stresses.
Mitigation strategies derived from this analysis may improve tunnel safety during construction in urban environments.
