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.
