摘要：
A generalized local dominant analysis method for shear band evolution was developed based on experimental and numerical of shear band to investigate the evolution mechanism of shear band in soil. The results show the influence of the stress concentration and redistribution in the tip area of the shear band in soil on the stress states and the further evolution of the shear band. The results were integrated into an extended finite element program with the results agreeing well with the model tests. Thus, the method accurately describes the influence of stress concentrations and redistribution in the tip area on the direction and evolution of shear bands and the mechanism for stress axes deflection in the tip area.
