 note = {The purpose of this study is to investigate the shape of yield surface of saturated clay for the decision of yield stress in stress-strain curves obtained by several drained triaxial tests.\nYield surfaces obtained experimentally in this study were compared with yield surfaces in Cam-clay model and Modified cam clay model, which are made use of elast-plastic constitutive equation of saturated clay.\nConsequently, obtained Yield surfaces differ from that of Cam-clay model and Modified cam clay model., 紀要論文},
