[FEB 2026] Ground water and pore water pressure are important components of a geotechnical analysis. When dealing with a simple phreatic water level, a complex transient dewatering scheme or even seasonal changes, both PLAXIS and Geostudio provide many options to assist with modelling your geotechnical problems.

In this session, Wai Liong Lai (Technical Support Engineer) and Kathryn Dompierre (Geotechnical Analysis User Success Manager) will provide insight into typical challenges with establishing representative pore water pressure conditions in both finite element (FE) and limit equilibrium (LE) geotechnical analyses. After the session you should understand:

Tips for selecting the ideal pore water pressure definition option for LE stability analysis. How to apply concepts of total head in stress and stability analyses. How to set more realistic hydraulic boundary conditions. Tips for interpreting pore water pressure results. Excess pore water pressures and its influence in stability analysis.
