Soil Movement & Stability Design

Ground movements can occur when the ground is subject to loading or unloading. Oasys geotechnical software provides a range of calculations for assessing and quantifying ground movements, equipping geotechnical engineers with simple yet robust solutions. Our software adds building and utility damage assessment capability, helping you to understand the effect of movements on your assets, including assessing slope stability.

Build around Oasys software

Build our products into your wider workflows to automate, optimise, or investigate sensitivity.

Building damage assessment

Calculate or import ground movements to perform building or utility damage assessments.


Calculate soil surface and sub-surface deformations under loads in 3D. Estimate short term settlements and longer term consolidation and creep settlements using empirical methods.

Slope stability

Assess the stability of slopes, perform factor of safety calculations for circular and non-circular slips.

The design of deep excavations and tunnels in crowded cities is a technical challenge for engineers. In these environments, engineers often need to look at the effects both below and above the ground (loading the ground and excavation). Our range of soil movement and stability software provides the tools needed to do this quickly and effectively.

To estimate the effect on surrounding structures, most urban tunnelling or excavation work requires ground movement as well as building and utility damage assessment. Producing these with different analysis programs and spreadsheets can be time-consuming and difficult to check. That is why we developed Xdisp, the industry standard for analysing and displaying results in clear 3D.
