From research on flat dilatometer test (DMT), the method of calculating bearing capacity of foundation by DMT is put forward. Take advantage of many DMT tested data from several projects in Shanghai, through the contrast and analysis with laboratory test, static sounding test and vane shear test, the formulae of calculating bearing capacity of foundation are given, and the precision of the formulae is studied. The conclusion shows that the method is feasible.
