Abstract
This contribution examines the applicability of ordinary kriging to interpolate the results of cone penetration tests or CPTs. The advantages of geostatistics are studied for two datasets of CPTs measured in a typical soil encountered in Flanders, Belgium: the Boom clay. Firstly the unit pile base resistance of a pile with a diameter of 0.4 m is studied, for a specific depth separately. Secondly the characteristic resistance of an axially loaded pile is considered. In that part of the study the whole profile is estimated at once, instead of estimating the value at a specific depth. From the study one can conclude that it is possible to estimate the bearing capacity accurately in a point if sufficient measurements are carried out in the immediacy of that point and that ordinary kriging can be a good method to make an estimation of the characteristic resistance of an axially loaded pile.

Notes
- 1.
Depth = distance below the top of the Boom clay.
- 2.
The term ‘all’ depths means the various depths from the top of the Boom clay till 7 m below the top with lags of 0.2 m.
