PLAXIS LE

Market leading limit equilibrium slope stability analysis

Essential LEM Slope Stability Analysis

PLAXIS LE is an advanced integrated slope stability analysis toolkit based on the Limit Equilibrium Method (LEM), uniquely providing both 2D and 3D capabilities in one application.

In projects involving engineering analysis of slope stability, groundwater flow, consolidation, or a combination of these complex scenarios, you can design more efficiently, save on construction costs, meet design standards and reduce risk to project timelines by combining LEM and FEA methods as appropriate.

Complete projects with PLAXIS LE digital workflows

Bring together powerful 2D/3D integrated geotechnical capabilities with a slope stability focus. Build conceptual models and geometry and integrate groundwater analysis. Represent materials spatially with advanced techniques and automate slope stability techniques. Utilize reinforcements, dynamic loads, and design standards. Determine material parameters with SoilVision Soils Database. Perform consolidation analysis. Manage various project workflows and scenarios.

Integrate groundwater analysis

Perform analysis on popular use cases, such as embankments, dams, reservoirs, and cover systems through earth structures and broader hydrogeological settings. Consider unsaturated groundwater flow, transient boundary conditions, and multi-year climatic effects, either as distinct models or combined with slope stability analysis. Calibrate complex 2D and 3D models with 1D analysis and Soilvision Soils database inputs.

Analyze slope stability within a comprehensive toolset

Create 2D and 3D limit equilibrium slope stability models of soil and rock slopes. Take advantage of the comprehensive set of search methods and over 15 analysis methods, including rapid draw-down, effective stress, and finite-element input. Leverage over 20 material strength models like Mohr-Coulomb, Hoek-Brown, Undrained, Anisotropic, and Unsaturated.

Determine material parameters with Soilvision Soils database

Determine material properties from site test data or search the database of 40,000+ soils. Estimate unsaturated soil properties through data mining, including GIS location. Manage constitutive model data for saturated/unsaturated flow, shear strength, compressibility, consolidation, thermal, pore-air flow, and contaminant transport analysis applications.

2D/3D integrated analysis

Bring together powerful 2D/3D integrated geotechnical capabilities with a slope stability focus. Enhance 2D or 3D limit equilibrium slope stability analysis with related unsaturated seepage groundwater flow estimation or stress analysis. Model slope stability with the finite element shear strength reduction method and perform small or large strain consolidation analysis.

Create conceptual designs and build models for analysis

Build 3D conceptual models in PLAXIS Designer for geotechnical analysis applications like slope stability, groundwater, consolidation, and stress/deformation. Move quickly from OpenGround, terrain mesh, and water level data to 2D and 3D analysis scenarios for an improved modeling workflow. Geometry creation methods include extrusion, multi-profile stitching, boreholes, fence diagrams, surface and layers, material volumes, and block models.

Automate slope stability techniques

Benefit from multi-plane analysis (MPA), which offers enhanced spatial slope stability analysis. Save time with automatic sliding direction determination, efficient search methods, probability analysis, and sensitivity analysis. Assess risk by rapidly solving extensive road, rail, riverbank, or urban areas.

Manage various project workflows and scenarios

Organize each modeling project by grouping scenarios and sequencing analysis from steady-state groundwater flow, to transient water level changes, through to slope failure back analysis and stabilization options. Link multiple models to a standard set of material parameters or initial conditions. Update an input once and batch analyze hundreds of models.

Represent materials spatially with various methods

Represent the subsurface as layer-cake geology, irregular material volume meshes (MVMs), and complex engineered earth structures. Define block models, use bedding guides with anisotropic material strength relationships, and utilize spatial variability methods. Reduce material strength through blasting zones in mining operations.

Perform consolidation analysis

Plan mine tailings facilities considering consolidation analysis, filling rates, and multiple deposition points. Maximize capacity from volume calculations and consolidation time predictions. Efficiently solve entire facilities with the automated pseudo-3D technique.

Utilise reinforcements and dynamic loads

Design to standards like Eurocode 7 or BS 8006. Incorporate over 10 typical slope reinforcements, such as soil nails, geotextiles, grouted tiebacks, and back-analyze for optimal spatial configurations. Determine the influence of point, distributed, and water loads, as well as seismic loading by pseudo-static or Newmark permanent displacement methods.
