Sand liquefiability assessment by Flat Dilatometer Test (DMT)

The aims of this paper are: (1) To summarize the available knowledge on the use of the flat dilatometer test (DMT) for evaluating sand liquefiability. (2) To formulate a new tentative correlation for evaluating the cyclic resistance ratio CRR from the DMT horizontal stress index Kd, to be used according to the "simplified procedure" (Seed & Idriss 1971). The proposed CRR-Kd correlation combines previous CRR-Kd curves with current correlations for evaluating CRR from CPT and SPT, translated using the relative density Dr as intermediate parameter.
