Plaxis 3D Tunnel is a specialized 3D finite element application for geotechnical analysis of tunnels and underground structures. It enables engineers to model soil–structure interaction and simulate realistic construction sequences, helping predict ground movements, lining forces, and the impact on nearby assets.
Key capabilities:
- 3D finite element modeling tailored for tunnels, caverns, shafts, and stations
- Staged construction workflows for excavation, temporary support, lining installation, grouting, and backfilling
- Advanced soil constitutive models (e.g., Mohr–Coulomb, Hardening Soil, Soft Soil) to capture nonlinear and time-dependent behavior
- Coupled groundwater flow and consolidation analyses for steady-state and transient conditions
- Structural elements (plates, beams, embedded piles/anchors) and interface elements for soil–structure interaction
- Automated mesh generation with local refinement in critical zones
- Import of tunnel alignments and geometry from common CAD formats; parametric setup for design variants
- Comprehensive outputs: displacements, stresses, pore pressures, settlements, and lining forces
- Safety and stability checks, including strength reduction (phi–c) analyses
- Typical applications include NATM/SEM tunnels, TBM-driven tunnels, road/rail metro systems, utility galleries, and underground caverns
This tool supports design optimization, risk mitigation, and compliance with geotechnical design standards throughout the tunnel project lifecycle.
