PLAXIS 3D is a powerful and user friendly finite element package intended for two-dimensional analysis of deformation and stability in geotechnical engineering and rock mechanics. PLAXIS is used worldwide by top engineering companies and institutions in the civil and geotechnical engineering industry. Applications range from excavations, embankment and foundations to tunnelling, mining and reservoir geomechanics.

PLAXIS 3D  abilities can be extended with three additional module : Dynamics and Plaxflow.


  • user-friendly interface (Windows©), for data input, stages definition and results analysis.
  • fully automatic mesh generation.
  • full set of material behaviour for soils (linear elastic, Mohr-Coulomb, Hardening Soil, Soft Soil, user-defined soil models…).
  • groundwater flow and consolisation analysis.
  • structural elements (plates, geogrids and anchors) and soil-structure interaction.
  • safety factor analysis (phi/c reduction).

3D DynamicsDynamics : soil and structures are often not only subjected to static loads due to construction in and on the ground surface but also to dynamic loads. When loads are powerful, like for example earthquakes, they may cause severe damages. In urban areas, vibrations can be generated due to pile driving, vehicle movement, heavy machinery or train travel. With the 3D Dynamics module Plaxis 3D can analyse the effects of vibrations in the soil.

Flow modeling in 3D PlaxflowPlaxflow : users can assign time dependant variation or fluxes to water levels, model boundaries, or soil boundaries to simulate various complex hydrological conditions. The input of the time dependant properties are based on harmonic, linear, or table functions. This allows the modelling of seasonal variations of river water level behind embankments and their effect on the overall slope stability. Precipitation, wells and drains can be included in the model, allowing pumping tests or other hydrological applications to be modelled.
