According to Terzaghi's bearing capacity formula, the coefficient of bearing capacity differ depending on the failure mode of the ground.It is necessary to determine the failure mode to calculate the bearing capacity, but the criterion has not been clarified so far.This research examined the shear strength and bearing capacity of diatomaceous soft rock by laboratory tests.The effect of the diameter of the specimen on the bearing capacity of a 3.5 cm diameter circular footing was investigated, and the relationship between the shear strength obtained from the triaxial UU test and the results of the bearing test was discussed.
