PLAXIS 2D WorkSuite - Geo-engineering projects made easy


Complete 2D FEM and LEM Geotechnical Software Package

Project teams and their requirements can vary. PLAXIS 2D WorkSuite integrates the powerful and user-friendly finite element and limit equilibrium analysis capabilities of PLAXIS applications for the design and analysis of soil, rock, and associated structures. 


Engineering companies and institutions rely on PLAXIS 2D for every geotechnical challenge - from excavations, embankments, and foundations to tunneling, mining, and reservoir geomechanics.  Intuitive workflows, robust calculations, reporting and analysis, together with user-friendly GUI with multi-select and edit options, are what makes PLAXIS 2D WorkSuite our most popular 2D geotechnical engineering software package. 

 PLAXIS 2D WorkSuite (formerly PLAXIS 2D Suite and SoilVision 2D Suite) offers a variety of key features, including:

  • Accurately calibrate material models. 
  • Advanced interoperability with the Bentley ecosystem. 
  • Automate tasks for improved efficiency with Python scripting.
  • Import CAD files for streamlined modeling, saving you time.
  • Strengthen reliability with the preeminent constitutive model library.
  • Access more functionality with sensitivity analysis and parameter variation.

Efficiently create models with a logical geotechnical workflow. Define everything from complex soil profiles or geological cross-sections to structural elements, such as piles, anchors, geotextiles, and prescribed loads and displacements. Use predefined structural elements and loading types in a CAD-like environment for fast and efficient model creation, allowing you more time to interpret the results.

Perform two-dimensional analysis of deformation and stability in geotechnical engineering and rock mechanics with PLAXIS 2D WorkSuite. Sound computation in PLAXIS 2D offers advanced features to consider creep, flow-deformation coupling through consolidation, and steady state groundwater or heat flow. Ultimate functionality can analyze the effects of vibration in the soil and perform ground response analysis, and liquefaction analysis using the PM4Sand and UBCSand models. Thermal modelling capabilities enhancement helps with the understanding of the effects of transient heat flow on the hydraulic and mechanical behavior of soils, rocks, and structures.

Enhance your 2D geotechnical solutions with the Bentley’s PLAXIS applications. Our reliable and user-friendly solutions save you time with an easy-to-use interface, and strengthens credibility with sound computational procedures.

PLAXIS 2D WorkSuite includes PLAXIS 2D Ultimate and PLAXIS 2D LE. 



Analyze factor of safety

Leverage our advanced strength reduction method analysis and accurately predict the degree of safety associated with the slope along with associated failure patterns. The strength reduction method is typically used for evaluating the safety of an embankment on soft soil with a high groundwater level and the impact of different construction rate. Safety factor evaluation analysis in PLAXIS can also be advantageously used in situations with strong structural interaction for which the evaluation of a failure mechanism on beforehand (as done in classical limit equilibrium analysis) cannot be achieved.

Apply absorbent model boundary conditions

Apply advanced model boundary conditions when dynamic analysis requires special boundary conditions. In addition to viscous boundaries, free-field and compliant base boundaries can also be selected to reduce spurious reflections of waves from reaching the model boundaries.

Automate repetitive tasks with native command line

Benefit from the additional access to specialized text commands that fully supports the PLAXIS modeling workflow and save valuable time in automating repetitive modeling tasks. Although all actions can also be accomplished through mouse clicks, the use of commands enhances the power of PLAXIS through automation workflows. Simply execute modeling operations and alternatively create PLAXIS model by alternatively entering text commands in the dedicated command line. Evaluate automatically generated text commands during interactive model-creating for further re-use or edition. Replay user-defined sets of text command for automated model creation.

Conduct dynamic analysis with earthquake data

In modeling the dynamic response of a soil or rock structure, the inertia of the subsoil and the time dependency of the load are considered. The time-dependent behavior of the load can be assigned through harmonic, linear, or table multipliers. Via table input, users can import real earthquakes signals to perform meaningful seismic design of jetties or foundations. Dynamic multipliers can be assigned independently in the x- and y-directions in PLAXIS 2D dynamics feature and x-, y-, and z-directions in PLAXIS 3D dynamics feature.

Define realistic and accurate initial conditions

Generate realistic initial stress and pore pressures fields in equilibrium with the soil weight through either K0-procedure or gravity loading. Automatically define state of over-consolidation for advanced constitutive models and set-up initial stresses in the soil body, considering both the influence of the weight of the material and the history of its formation. The field stress initial calculation complements the gravity-based initial stress definition and makes it easier to define the in-situ stress for the non-uniform deep ground conditions, such as those encountered in deep tunneling or reservoir geomechanics.

Determine stress change due to thermal loading

Analyze displacements or the rotation of stress due to temperature changes. Coupling between thermal loading and mechanical process is required when the temperature change in soils results in thermal stresses. An example is the deformation of a navigable lock due to sunlight absorption when the lock is empty.

Evaluate flow-deformation coupling through consolidation analysis

Precisely evaluate the mechanical process by which soil gradually changes volume in response to a change in pressure over time. Evaluate long-term settlement of foundations or earthworks over weak and non-permeable soil layer, such as marine clay. Safely evaluate possible technical risks associated with consolidation in areas like land reclamation, construction of embankments, tunnels, and basement excavation in clay.

Obtain accurate steady-state flow analysis for dewatering and groundwater control

Easily generate non-hydrostatic pore water pressure distribution in the initial hydraulic gradients or after dewatering. Leverage water-level definition for fast and straightforward generation of boundary conditions for groundwater flow analysis. Evaluate steady-state temperature distribution for underground cable system of retaining wall under severe climatic conditions.

Optimize ground freezing design

Whether the ground freezing is artificial to stabilize weak ground or natural you can study the complex interplay between the velocity of groundwater flow, temperature of the freezing pipes, and their effects on the formation of an ice wall through the various boundary conditions.

Perform time-dependent flow analysis

Go beyond the default options of steady-state groundwater flow analysis PLAXIS Advanced with the PLAXIS Ultimate. Assign time dependent variation or fluxes to water levels, model boundaries, or soil boundaries to simulate various complex hydrological and/or thermal conditions. The input of the time dependent properties is based on harmonic, linear, or table functions. This allows seasonal variations of river water levels behind embankments and their effect on the overall slope stability to be modeled. Precipitation, wells, and drains can be included in the model, allowing pumping tests or other hydrological applications to be modeled.
