    • 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.
  • 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.
  • 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.

  • 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.
  • 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.
  • 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.
  • 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.
  • Utilize 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.
