Atlaned Field · SPT, CPT, and liquefaction

Turn SPT and CPT records into soil profiles and parameters.

Run SPT and CPT analysis against the boreholes in your project. Field classifies soil behaviour, applies the corrections and correlations you choose, and checks liquefaction triggering layer by layer.

  • Robertson soil behaviour type charts (1990, 2010, 2016)
  • SPT corrections and correlations, including Peck, Skempton, and Liao & Whitman
  • Liquefaction triggering: Boulanger & Idriss (2014), Robertson (2010), NCEER (1998)
  • Save calculation branches and recalculate with new inputs

Atlaned Section · Cross-section designer

Draw cross-sections from the boreholes you already have.

Choose boreholes from the project and build a section with strata, groundwater, and labels in one drawing. Adjust the details, then export it for your report.

  • Sections built from project boreholes
  • Groundwater lines and section details
  • Measurement and label placement tools
  • Export as SVG or PNG

Atlaned Slide · Slope stability

Check slope stability with the methods reviewers expect.

Import or draw the slope geometry, assign materials and water conditions, and compare limit equilibrium methods side by side. Every run is kept in a ledger, so you can see how a result changed.

  • Bishop, Janbu, Spencer, and Morgenstern-Price
  • Geometry import from DXF and CSV
  • Piezometric lines, pore pressure ratio (ru), and seismic coefficient
  • Anchors, scenarios, and slice-by-slice forces

Atlaned Quake · Seismic site response

See how the ground responds to an earthquake.

Build a soil column, choose input motions, and run one-dimensional site response analysis. Quake guides you step by step, from site setup to results.

  • Equivalent-linear and nonlinear analysis
  • Modulus reduction and damping curves, including Darendeli (2001) and Menq (2003)
  • Response spectra and amplification
  • Results plotted against depth
