Drilled and driven piles.

Analysis of filter stability of soils after Cistin/Ziems and suffosion safety after Kenney/Lau and Burenkova.


  • Manual system data input or data import from the GGU-SIEVE program (determination and presentation of grain size distribution curves, Version 14 and upwards)
  • Consideration of soil grain shape compliant with DB guideline 836 (module 836.4602A01: Tiefenentwässerungen, Nachweise der Filterstabilität von Filtern/Dräns (Deep drainage, analysis of the filter stability of filters/drains), 1st revision, 01 October 2008)
  • Visualisation of the allowable interval ratio between the filter and the protected soil as a function of their uniformity coefficients in the Cistin/Ziems diagram
  • Input data and analysis results displayed in a legend
  • Examples from DB guideline 836 and Merkblatt Anwendung von Kornfiltern an Wasserstraßen (MAK) published by Bundesanstalt für Wasserbau (BAW) in Karlsruhe, 1989
  • User-defined design of output sheet
  • Print or copy screen sections, e.g. for transfer to a word processor
  • Integrated Mini-CAD system for additional annotation of graphics
