ABSTRACT For a long time, size effect measured on failure properties of geomaterials have been explained by the randomness of material properties. However, the analysis of scaling law shows that the probabilistic aspect does not introduce an internal length that is necessary to reproduce experimental measurements. This is done with the Bazant's size effect law whose parameters can be deduced from experimental results or from numerical ones using regularized approaches of failure models.
