[CS2-08] A consideration on bearing capacity evaluation method of diatomaceous soft rock
キーワード：珪藻質軟岩、3軸UU試験、支持力、ひずみ軟化、残留強度、ピーク強度
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.
