What you'll learn

Design & Analyze Foundations – Model and evaluate square, circular, strip, and combined footings under various loads using PLAXIS 3D for geotechnical analysis.

Calculate Bearing Capacity – Assess ultimate and allowable bearing capacity on sand, clay, layered soil, and rock, considering water table and foundation depth.

Simulate Complex Problems – Analyze underground cavities, trenches, dewatering, and buried structures to understand their effects on foundation performance.

Enhance Modeling Accuracy – Optimize mesh size, use symmetrical quarter models, and compare Mohr-Coulomb vs. Hardening Soil models for better foundation analysi

Requirements

A basic understanding of soil mechanics and foundation engineering is helpful but not mandatory. Access to PLAXIS 3D is recommended for hands-on practice, though theoretical concepts can still be learned without it. Civil or geotechnical engineering students and professionals will benefit most, but motivated beginners can also follow along. A computer with Windows OS capable of running PLAXIS 3D smoothly is ideal for practical modeling and analysis exercises.
