Introduction to PLAXIS 2D
2. Course Objectives
- Understand the fundamentals of the Finite Element Method (FEM) as applied to geotechnics.
- Navigate the PLAXIS 2D interface (Input, Calculation, Output).
- Select appropriate constitutive models (Mohr-Coulomb, Hardening Soil, Soft Soil).
- Simulate construction stages (excavation, embankment, tunneling).
- Perform deformation, consolidation, and stability (phi/c reduction) analyses.
- Interpret output: displacements, stresses, pore pressures, and failure mechanisms.
Alistair smiled, kneeling beside her. "Think of the geometry. You’re trying to force a single water level where there are two hydraulic regimes. Use the Water Conditions mode to define a user-defined water level. Don’t let the software assume; tell it exactly what the ground is doing."
