What is Finite Element Analysis in Geotechnical Engineering?

Geotechnical engineering uses computer-based Finite Element Analysis (FEA) to simulate how soil, rock, and structures behave under load circumstances. The system splits complicated ground designs into smaller parts to measure force movement and material response. GEA assists engineers in checking ground stability since it shows where and how ground movement occurs when soil reacts to external forces.
