Shaft Resistance

Determination of shaft resistance qs should be part of the geological survey.

Recommended values of resistance qs [kPa] can be found in professional literature for specific soils and structure types:

  • for bored piles:

qs

non-cohesive soil

cohesive soil

qc

cu

7,5

15

25

60

150

250

55-80

105-140

130-170

30-40

50-65

65-85

  • for driven piles:

qs

non-cohesive soil

cohesive soil

where:

qc

-

cone penetration resistance, CPT [MPa]

cu

-

total cohesion of the soil [kPa]

ssg*

-

settlement at shaft resistance activation

sg

-

limit settlement

Deq

-

pile diameter

Intermediate values may be linearly interpolated.
