Analysis according to CTE-DB SE-C

The bearing capacity of foundation soil composed of rocks according to the CTE-DB SE-C standard is given as follows:

where:

σcd

-

uniaxial compressive strength of rock

Ksp

-

loading factor

s

-

distance of discontinuities

B

-

total foundation width

a

-

opening of discontinuities

The input parameters for the calculation must meet the following conditions:

  • Distance of discontinuities s min. 300 mm
  • Opening of discontinuities a max. 5 mm (resp. 25 mm, if filled with soil or rock debris)
  • Ratio of distance of discontinuities s to foundation width B

  • Ratio of opening of discontinuities a to distance of discontinuities s

The resulting value of the bearing capacity of the foundation soil Rd is already reduced by the coefficient γR = 3.0, which is included in the Ksp coefficient. The program therefore does not react to the defined reduction coefficient of the vertical bearing capacity in the "Analysis settings".
