DC-Pilegroup pro

The DC-Pilegroup pro program is used to calculate and design combined pile-raft foundations (CPRF) taking into account the elastic support of the raft and the pile-pile and pile-raft interactions.

Sample video for working with the program DC-Pilegroup: Analysis of pile groups and Combined Pile Raft Foundations (CPRF) Input, configuration, analysis and result output


  • Selectable pile types: bored piles, displacement piles (driven piles) and micro piles (grouted piles) 
  • As compression piles or tension piles
  • Vertical or with an inclination
  • Combined pile-raft foundation (CPRF) with consideration of the pile-pile and pile-raft interactions
  • Calculation of a bedded raft without piles is possible
  • Variable soil stratification with specification of the characteristic parameters: skin friction, peak pressure and stiffness modulus for the foundation
  • The characteristic values for the skin friction and the peak pressure specified by DIN 1054, ÖNORM B 1997 and the EA Recommendations are available for cohesive and non-cohesive soils and rock
  • Multiple load cases with vertical and horizontal concentrated loads and line loads as well as concentrated moments and line moments, area loads
  • Automatic generation of the load case combinations with the combination coefficients psi
  • Calculation and representation of the pile internal forces, the pile settlements incl. interactions, the soil pressure and the deformations as well as of the raft internal forces
  • Calculation of the elastic support of the raft taking into account the bearing effect on the piles (FEM analysis with isoparametric quadrangular elements)
  • Calculation of the CPRF taking into account the influence of the piles on the other piles and the raft and vice versa in accordance with El Gendy, Hanisch, Kany
  • Calculation of the load distribution on the piles and the required pile lengths
  • Automatic iteration to find the state where the raft foundation and the pile settlement are in equilibrium
  • Design of the piles and the raft, calculation of the required reinforcement and, if necessary, a punching shear analysis at the pile heads
  • 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
