要約:Rotational Multiple Yield Surface Framework (RMYSF) is an anisotropic soil volume change model developed to integrate shear strength in characterising the soil volume change behaviour from the standpoint of the stress-strain response. The anisotropic soil volume change behaviour is described from the interaction between applied stress represented by the Mohr-Coulomb circle and shear strength in terms of curved-surface mobilized shear strength envelope. This research work is to enhance the current method of RMYSF using normalisation of axial strain to predict stress-strain behaviour. A series of triaxial tests has been conducted on Malaysian sedimentary sandy residual soil grade VI. The stress-strain curves and volume change behaviours were analysed using this enhanced method. Subsequently, the enhance method is apply to predict the soil stress strain respond and make comparison with the actual laboratory stress-strain curve. Essentially the normalised method of RMYSF has improved the accuracy of the prediction as presented in the paper. © 2019 IOP Publishing Ltd. All rights reserved.
