GGU-SIEVE

Evaluation and presentation of grain size distribution

Evaluation and presentation of grain size distribution via:

  • Sieve analysis
  • Hydrometer analysis
  • Combined sieve and hydrometer analyses

Capabilities:

  • Variable sieving input (before/after sedimentation, partial mass weights, cumulative weight, in [g] or [%])
  • Define and save individual sieve sets
  • Input and save various hydrometers with their constants
  • Output of test results as graphics of percentages of grain fractions and as laboratory logs
  • Determine soil types to DIN 4022, ISO 14688-1, SEP or ASTM
  • Compute uniformity coefficients U and coefficients of curvature Cc
  • Determine the hydraulic conductivity to Hazen, Beyer, Mallet/Pacquant or Seelheim, including the respective validity rules
  • Determine the grain index
  • Determine the soil group and frost resistance to German standards (DIN), Swiss standard SN 670 008a or USC (ASTM 2487)
  • Take the coefficient of plasticity and the liquid limit into consideration for fine-grained soils
  • Visualise Therzaghi and/or USBR filter criteria
  • Estimate friction angle after Lang/Huder
  • Determine any number of passage values (e.g. grain sizes at d10, d30, d50, d60)
  • Mix grading curves using variable constituents of existing grading curves
  • Separate 2 grading curves to compute suffosion
  • Calculate filter stability to Cistin/Ziems via export to GGU-FILTER-STABILITY application
  • Determine grading curves using user-definable smoothing out procedures
  • Variable grading curve visualisation (user-definable line types and colours)
  • Graphics for up to 630 mm grain size diameter (> 200 mm = blocks)
  • Visualise grain size envelopes or boundary ranges via Extra GSDs (grain size distributions)
  • Cumulate up to 50 existing grading curves via Extra GSDs
  • Design your own graphics and log pages
  • Print or copy screen sections, e.g. for transfer to a word processor
  • Integrated Mini-CAD system for additional annotation of graphics
