FEA and limit equilibrium techniques are well-established tools for assessing the behaviour of soils and adjacent structures. We have provided PLAXIS software & services since 1996 – the most popular solution for detailed analysis of ground movement, foundations, tunnels, slopes, excavations and problems involving consolidation and groundwater flow.
Through our dedicated software and experience in the civil engineering, offshore and nuclear industries, we enable our clients to accurately model the behaviour of soils and rock mass. PLAXIS is specifically developed for the simulation of staged construction, consolidation & settlement, bearing capacity and many other applications. We also support TALREN for rapid slope stability design and assessment.
Our geotechnical analysis software and services help:
Predict ground movement, structural deflections and loads with accuracy
Reduce conservatism within designs
Understand performance changes due to loading & material uncertainties

We have in-depth knowledge of soft soil, hardening soil, small-strain stiffness, jointed rock and creep behaviour, including Mohr-Coulomb, Hoek-Brown, Modified Cam Clay and Sekiguchi-Ohta materials.
Dynamic response results from a PLAXIS simulation can help develop a spring/damper model for a separate, more detailed analysis of above-ground structures. We can also support ANSYS FEA users with their application of in-built constitutive models.

The ease of use and value gained from PLAXIS means that most of our geotechnical clients prefer to lease or purchase the software, assisted by our tuition and technical support services. 2D and 3D versions are available to suit user requirements, including options for office-based and site licensing.

Our intentionally-recognised and long-running Standard Course on Computational Geotechnics training course has been attended by over 300 engineers. This popular 4 day event combines fundamental theory with hands-on workshops, delivered by leading experts in soil modelling.
For clients who require simulation capability at short notice but do not have the internal capacity or skills, we provide geotechnical consulting services. We can also call upon a range of technical partners if necessary, including the Expert Services team at Plaxis bv.
