DC-Software products



The DC-Nail program is used to calculate embankments secured with nails in accordance with the block sliding approach. The internal and external stability verifications as well as the design of the nails and the shotcrete wall are performed.







  • Any slope shape and stratification can be defined
  • The graduation of the wall is possible
  • Any number of excavations stages
  • Any course of the groundwater can be defined
  • For the accurate internal modelling of the structural system (e. g. ground surface and soil stratification), it is possible to import DXF graphics as a background
  • Several load cases with vertical and horizontal concentrated loads and line loads can be defined and earthquake loads can be considered
  • Calculation according to the general block sliding approach
  • Verifications of the internal and external stability: sliding mass investigation, overturning, sliding, ground failure and base failure
  • Verification of the nails: determination of the nail forces, steel tension, transfer of the nail forces into the soil, calculation of the nail lengths and diameters
  • Design of the shotcrete wall: as a slab or a continuous girder, determination of the reinforcement, punching shear analysis at the nail head plate
  • Detailed output of the individual load cases as text and graphics
  • Output options: printer, PDF
  • Interfaces: RTF export to MS Word, graphic export in JPG format, DXF export
