How PLAXIS 2D & 3D Can Help Your Geotechnical Design

Geotechnical applications often require advanced constitutive models for the simulation of the non-linear, time-dependent and anisotropic behaviour of soils and rock.

In addition to traditional Mohr-Coulomb and linear elastic materials, further models have specifically been developed with parameters that can be readily determined using standard soil testing methodologies. Pore pressures in the soil can be accurately captured for both simple hydrostatic, water-table derived problems as well as more complex situations where artesian conditions, groundwater flow and soil excavation drive the pore water pressures.

The software includes geometry creation tools and automated settings to allow geotechnical problems to be analysed efficiently & accurately with the minimum of training.

Based on the finite element method, which overcomes limitations associated with classical calculation techniques, PLAXIS has been developed specifically to predict the deformation and stability of soil structures under static and dynamic loadings, as well as groundwater and heat flow.

Renowned for its ease of use, accuracy and speed, typical PLAXIS applications include excavations, foundations, embankments and tunnels within the civil engineering, nuclear, oil & gas and renewable energy industries.

PLAXIS 2D offers a complete 2D solution for geometric design and analysis, accurately simulating both non-linear, anisotropic soil/ rock behaviour and interaction with structures. Optional dynamic, transient groundwater flow and thermal capabilities are available.

Software Options

PLAXIS 2D Basic is the most widely used  2D simulation solution for deformation and stability analysis of multiple construction stages within geotechnical engineering, considering steady-state groundwater flow for saturated and partially saturated conditions.

2D Dynamics includes the non-linear, time-dependent behaviour of soils and/or rock for modelling wave propagation due to seismic activity and construction vibrations.

2D PlaxFlow includes transient groundwater flow modelling.

2D Thermal includes thermal heat flow within soils, and its effects on groundwater flow and soil behaviour, for civil, environmental, energy, mining and polar engineering applications.

Certain geotechnical design challenges can only be analysed effectively in 3D. 

?PLAXIS 3D provides accurate and robust soil and soil-structure interaction simulation capabilities through an efficient workflow, ideal as an integral design tool. Optional dynamic and transient groundwater flow capabilities are available. 

Software Options

PLAXIS 3D Basic is a complete solution for 3D deformation and stability analysis of non-linear soil/rock behaviour and complex structures, It supports 3D geometry import and creation while including tools for rapid soil layer definition and tunnel design.

3D Dynamics includes the non-linear time-dependent behaviour of soils and/or rock for modelling wave propagation due to seismic activity and construction vibrations.

3D PlaxFlow includes transient groundwater flow modelling.
