An evaluation of the allowable bearing capacity of Kanto Loam is ordinary determinated by the curves resulted from plate loading tests, i.e., deformation and failure characteristics under each loading stage. Conclusions are as follows ; (1) Characteristic of Kanto Loam Settlement are to be mostly regarded as compressive deformation. (2) Characteristics of Kanto Loam-failure are (a) no sliding surface in the soil and (b) occurrence compressive zone just under the plate. And pattern of Kanto Loam-failure is similar to punching shear failure. (3) Relationship between loading pressure and settlement has a trend to change sharply around a point of consolidalion yield pressure and after passing this point, settlement increases greatly. (4) Long allowable bearing capacity ranges from 10 to 20 t/m^2. This capacity nearly equales to the value of 1.5 times-yielding pressure. (5) Value of bearing-capacity factor (N_c) equales almost to Terzaghi's factor (N_c) in local shear failure.
