This paper presents a compilation of documented case histories to include comparisons of DMT-predicted vs observed settlements, to review the available experience on the use of DMT for settlement calculations and to evaluate the accuracy of settlement predictions based on DMT. The available data indicate that, in general, the constrained modulus obtained by DMT (Mdmt) can be considered a reasonable "operative modulus" (relevant to foundations in "working conditions") for settlement predictions based on the traditional linear elastic approach. Attention is also given to the determination of the strain range appropriate to Mdmt, in view of the possible use of Mdmt for settlement predictions based on non linear methods by taking into account the decay of soil stiffness with strain level.
