Essential LEM Slope Stability Analysis


Spend your time where it’s most critical.

Valuable analysis time can be lost in tedious data input requirements and extensive solver times in numerical modeling applications.

In projects involving engineering analysis of slope stability, groundwater flow, consolidation, or a combination of these complex scenarios, users are choosing tools to design more efficiently, save on construction costs, meet design standards, and reduce risk to project timelines. Teams rely on automated techniques, data management through to analysis workflows, and access to comprehensive analysis methods to find solutions.

Save time with methods that automate slope stability techniques and can perform thousands of calculations with minimal inputs. With PLAXIS LE, users can reliably complete numerous limit-equilibrium slope stability models with intuitive workflows and fast analysis. Advance your digital workflows with the ability to design 3D geometry and analyze both 2D and 3D scenarios in one application. Efficiently represent materials spatially with various methods, as well as utilize the SOILVISION Soils Database for resourceful material management.

Managing complex geotechnical projects with multiple scenarios doesn’t have to be impossible. Equip your team with the ability to quickly and confidently create common or complex real-world 2D or 3D numerical models and analyze with credibility.
