Soil Idealization - Constitutive Models

Z_SOIL.PC uses the most robust numerical algorithms to simulate nonlinear, time dependent, soil behavior, according to the Tresca, Mohr-Coulomb w. dilatancy cut-off, Rankine, Drucker-Prager-Cap, and Cam-clay models for soil, multi-laminate for layered media and schists, Hoek-Brown models for rock, Menétrey-Willam (with softening) for concrete and Biot models for the consolidation and two-phase problems, monotonic ECP-Hujeux model for complex soil behaviours; user defined models capability for continuum, user defined fiber model for beams.

The program can efficiently simulate any types of load and soil stress conditions, for example:

• Gravity fields and initial stress conditions

• Water table and water pressures under steady state or transient conditions, including time dependent boundary conditions

• Drained and undrained soil conditions

• Explicit definition of excavation/construction sequences

• Imposed displacement fields

• Concentrated and distributed loads applied at the boundaries of the soil medium • Unloading control for convergence analysis in tunnels

• infinite or semi-infinite media.
