AI Summary
- Reviews a São Paulo Metro project using 3D FEM analysis to evaluate tunnel behavior in residual porous clayey soils.
- Shows how construction staging and excavation sequence influence settlement prediction and deformation control.
- Demonstrates how support systems are adjusted based on soil–structure interaction and field monitoring.
- Connects numerical analysis with on-site decision-making to refine construction strategies and reduce settlement risks.
