| Abstract: | Some concepts of probabilistic modelling of soil profiles are discussed. In particular, the theory of random field and some of its recent developments are discussed. The theory takes account of the uncertainty arising from the variability of soil properties and also the statistical uncertainty arising from sampling. The paper also discusses a method for assessing the reliability of the axial bearing capacity of piles in cohesive soils and the procedure is illustrated by means of an example. |
