GGU-FILTER-STABILITY

GGU-Filter-Stability GGU-FILTER-STABILITY

Analysis of filter stability of soils after Cistin/Ziems and suffosion safety after Kenney/Lau and Burenkova, as well as for geosynthetics


Only available in german language. 

Analysis of material transport in non cohesive soils using the following methods: 

  • Filter stability after Cistin/Ziems 
  • Suffusion safety after Kenney/Lau 
  • Suffision safety after Burenkova 
  • Interface erosion at layer boundaries complient with TAW  

described in Code of Practice “Material Transport in the Soil“ (German: “Merkblatt Materialtransport im Boden (MMB)“, published by Bundesanstalt für Wasserbau (BAW) in Karlsruhe, 2013)  

and 

  • filter stability of geotextile filters; 

described in DWA-M511 Code of Practice “Filters using geosynthetics”, (German: “Filtern mit Geokunststoffen“, 2015).

Capabilities:

  • Manual system data input or data import from the computer program GGU-SIEVE  (determination and presentation of grain size distribution curves, Version 14 and upwards) 
  • For interface erosion at layer boundaries, permeabilities for common soils can be selected from an expandable database 
  • 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) 
  • Visualization of the allowable interval ratio between the filter and the soil to be protected as a function of their uniformity coefficient in the Cistin/Ziems diagram 
  • Design of geotextiles and search for optimal product following the analysis of the filter stability of geotextile filters compliant with the DWA-M511 Code of practice 
  • Visualization of suffosion saftey after Kenney/Lau, very convenient as a data import from the computer program GGU-SIEVE possible 
  • Visualization of suffosion saftey after Burenkova 
  • Visualization of interface erosion at layer boundaries in a model compliant with TAW  
  • 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  
  • 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
