PLAXIS 3D: the tool that transforms your soil analyses into reliable decisions

3D soil analysis, reliable results

PLAXIS 3D allows geotechnical engineers to perform advanced 3D finite element analyses for ambitious projects in the civil, mining, energy and environmental engineering sectors.

Study excavations, surface, pile and offshore foundations, embankments, soil improvement measures and tunnels. Consider static, dynamic or seismic loads as well as complex hydrological conditions with temporal variations in water level and flow.

Raise your geotechnical projects to the next level with PLAXIS 3D.

What is PLAXIS 3D?

PLAXIS 3D incorporates all the essential features to easily perform daily soil and rock deformation and safety analyses. This complete software for the design and analysis of soils, rocks and associated structures allows you to model in complete 3D.

What is PLAXIS 3D Advanced?

PLAXIS 3D Advanced includes all the features of PLAXIS 3D, while enriching your geotechnical design capabilities with advanced features and additional material models.
Vous pouvez prendre en compte le fluage ou le couplage écoulement‑déformation via l’analyse de consolidation. De plus, grâce au solveur multicœur, vos calculs sont réalisés plus rapidement qu’avec PLAXIS 3D classique.

What is PLAXIS 3D Ultimate?

PLAXIS 3D Ultimate expands the capabilities of PLAXIS 3D Advanced, allowing you to analyze the effects of vibrations in the ground, whether seismic or related to traffic and mobile charges. You can also simulate complex hydrological conditions through temporal variations in water level or flow functions on model and soil boundaries.

3D geotechnical dynamic modelling

PLAXIS 3D Ultimate is simple to use and designed for advanced seismic analysis. Ideal when vibrations exceed low frequencies, it allows to:

  • Study the impact of natural or man-induced vibrations on the ground

  • Analyze the effects of earthquakes, pile strikes, vehicle traffic, heavy machinery or train crossings

  • Accurately calculate vibration effects with dynamic analyses when load frequency exceeds natural soil frequency

  • Conduct soil response and liquefaction analyses with the UBCSand model

3D underground flow modelling

PLAXIS 3D Ultimate goes beyond the steady-state groundwater flow analysis:

  • Simulates unsaturated, temporal and anisotropic soil behaviour

  • Permet le calcul simultané des variations de pression interstitielle et de déformations grâce à une analyse couplée flux‑déformation

  • Offers a "Flow-only" mode to exclude movements and constraints if only underground flow interests you, for more simplicity

What is Geotechnical Analysis 2D WorkSuite?

Geotechnical Analysis 3D WorkSuite includes PLAXIS 3D Ultimate and GeoStudio 3D Advanced, providing the most complete 3D option for your geotechnical projects.

With GeoStudio 3D Advanced you can:

  • Conduct 3D slope stability analyses for soils and rocks

  • Simulating groundwater flow under various conditions

  • Integrate pore pressure results into your stability analyses for more accurate and advanced assessments

Key Features

Address your infrastructure challenges reliably

Generate and easily adapt construction sequences for excavations. Perform steady-state groundwater circulation calculations, including flow parameters, boundary conditions, drains and wells. Model the interactions between soil and foundation, such as slips or gaps, using integrated pile interfaces and elements. Get reliable results with realistic soil models and a full portfolio of visualization tools.

To meet the unique challenges of soil-structure interactions, PLAXIS 3D offers different types of calculations: plastic analysis, consolidation and safety. A wide range of material models predict the behaviour of various soils and rock types. Combined with robust calculations, they guarantee reliable results. View these forces in multiple ways and use cross-sections to examine certain areas in detail.

Create logical geotechnical workflows that cover the entire project, from the import of subsurface data to the design, analysis and production of various deliverables.

Ability to manage large CAD files

PLAXIS's ability to work effectively with design, construction and contractor teams is its main asset. At meetings, I can respond quickly to stakeholder requests by adjusting geometry and sharing different scenarios. The ability to model instantly allows us to avoid endless exchanges of emails and phone calls.
