Abstract
The investigation was performed to indicate the usage of the technical terms of the allowable bearing capacity, the allowable bearing power and the allowable stress in analysis of the foundation on the ground. The allowable stress named globally for a material is classified locally according to the stress conditions of compression, tension, shear and bending. The allowable stress means the allowable bearing capacity for the ground. The allowable stress is obtained by use of the ultimate bearing capacity in taking account of the safety factor.
