Geotechnical
PLAXIS 2D
The most used tool for geo-engineering




PLAXIS 2D is a finite element package intended for the two dimensional analysis of deformation and stability in geotechnical engineering. It is equipped with features to deal with various aspects of geotechnical structures and construction processes using robust and theoretically sound computational procedures.

With PLAXIS 2D the geometry of the model can be easily defined in the soil and structures modes, after which independent solid models can automatically be intersected and meshed. The staged construction mode allows for simulation of construction and excavation processes by activating and deactivating soil clusters and structural objects. The calculation kernel enables a realistic simulation of the non linear, time dependent and anisotropic behaviour of soils and/or rock. Since soil is a multi phase material, special procedures allow for calculations dealing with hydrostatic and non hydrostatic pore pressures in the soil. The output consists of a full suite of visualization tools to check the details of the 2D underground soil-structure model.

Typical PLAXIS applications include: assessing street level displacements during the tunnel construction, consolidation analysis of embankments, soil displacements around an excavation pit, dam stability during different water levels, and much more.

PLAXIS 2D is a user friendly geotechnical program offering flexible and interoperable geometry, realistic simulation of construction stages, a robust and reliable calculation kernel, and comprehensive and detailed post-processing, making it a complete solution for your daily geotechnical design and analysis

2D dynamics



The 2D Dynamics module is an extension to PLAXIS 2D. Geotechnical applications require advanced constitutive models for the simulation of the non linear, time dependent and anisotropic behaviour of soils and/or rock. Although the modelling of the soil itself is an important issue, many projects involve the modelling of structures and the interaction between the structures and the soil. 2D Dynamics offers the tools to analyse the propagation of waves through the soil and their influence on structures. This allows for the analysis of seismic loading as well as vibrations due to construction activities. 2D Dynamics offers the possibility to perform dynamic calculations in individual calculation phases.


2D PlaxFlow

2D PlaxFlow is an add on module to the PLAXIS 2D program. Geotechnical applications require advanced numerical tools and constitutive models for the simulation of the non-linear, time dependent and anisotropic behaviour of soils and/or rock in saturated and partially saturated situations. For many practical applications it is necessary to take into account both deformation and groundwater flow. For time dependent analysis, this leads to mixed equations of displacement and pore pressures, called coupled hydro-mechanical approach, which have to be solved simultaneously. This type of analysis which is based on Biot’s theory of consolidation enables the user to simultaneously calculate deformation and groundwater flow with time-dependent boundary conditions in saturated and partially saturated soils.
