Plaxis Training for geotechnical Engineers

Plaxis FE 2D Training is aimed to equip a fresher to learn faster and master all the essential skills.

Plaxis FE 2D walkthrough, Mohr coulomb theory and Foundation analysis:

• Introduction to User Interface

• Meshing, points, and nodes selection for output
• Create water surface
• Staged construction
• output

Mohr coulomb model:

• Theory of soil strength using mohr coulomb model (elastic perfectly plastic)
• Model Parameters and field and lab tests to determine the parameters.

Foundation problem:

• Concept of axisymmetric and plane strain simulation
• Calculate settlement under target load (Strip and isolated circular footing)
• Using prescribed displacement find out allowable load
• Solve proactive problems.

Construction of Embankment over soft clay

• Consolidation and Undrained behavior in Plaxis

• Sensitivity analysis (critical parameters)
• Staged construction
• Target min excess pore water pressure
• Output
• Use of drains
• Safety analysis
• Updated mesh and updated water pressure
• Solve practice problem
• Bonus: slope stability measures such as toe protection by anchors, slope protection by soil nails etc.

Deep Excavation:

• Ground water flow analysis in plaxis
• Hardening soil model
• Limitations of Mohr coulomb model to simulate unloading
• Concept of OCR and significance in excavations.

Dry excavation supported by sheet pile or soldier pile wall

• Soil parameters
• Embedded pile, sheet pile wall
• Sensitivity analysis (critical parameters)
