DC-Lamella

The DC-Lamella programme can be used to calculate the stability of diaphragm wall lamellae in accordance with DIN 4126. In the calculation, both a guide wall and corner lamellae can be considered according to the method of Triantafyllidis, Vogelsang and Grandas-Tavera.

Analysis of the stability of diaphragm wall lamellae acc. to DIN 4126:2013 and Eurocode 7, incl. corner panels acc. to Triantafyllidis

161,57MB

Description
  • Entry of the dimensions of the diaphragm wall and the guide wall and of the required parameters of the supporting liquid
  • Consideration of corner lamellae according to the approach of Triantafyllidis, Vogelsang and Grandas-Tavera
  • Variable horizontal soil stratification
  • Horizontal or inclined ground surface with up to two slopes
  • For the accurate internal modelling of the structural system (e. g. soil stratification), it is possible to import DXF graphics as a background
  • Maximally ten area loads can be applied individually or in combination for the pressure at rest on the guide wall and the lateral pressure on the sliding wedge
  • Bilinear assumption of lateral pressure according to DIN 4126
  • Consideration of the guide wall with a supporting pressure at rest
  • Calculation of the loss of supporting liquid through ingress in the soil
  • Verification of the safety against groundwater ingress into the lamella and against displacement of the supporting liquid
  • Verification of the safety against sliding of individual grains or grain groups
  • Verification of the safety against sliding surfaces in the ground threatening the lamella
  • Verification of the required liquid limit of the supporting liquid
  • Detailed representation also in graphics of the utilisation, the pressure gradient, the penetration depth, the support force, the earth pressure and the flank friction
  • Output options: printer, PDF
  • Interfaces: RTF export to MS Word, graphic export in JPG format, DXF export
