In this study, the geotechnical data obtained from the boring logs and geotechnical tests in Myanmar were compared to those of Japanese data. The distributions of the particle density and the activity of both clays were almost similar. The compressibility indexes of Myanmar clays at the same liquid limit were about half of those of Japanese clays. The coefficients of consolidation of Myanmar clays at the same liquid limit were much smaller than those of Japanese clays. The average strength increment ratios, which were obtained from the relation between unconfined compressive strength and the effective overburden stress in the normally consolidated ground, were 0.225 two third of Japanese clays.
