This paper deals with the use of the flat dilatometer test (DMT) for evaluating the in situ horizontal coefficient of consolidation (ch) by dissipation tests. Two different procedures developed for this purpose, the DMTC method by Robertson et al. (1988) and the DMTA method by Marchetti & Totani (1989), are briefly recalled and some comparative results discussed. Four case histories are presented where ch values determined by DMT dissipation tests performed at different well documented NC to OC clay sites in Italy are compared with the corresponding values determined in the laboratory or backfigured from interpretation of field measurements.
