The Role of Internal Characteristic Length in Slope Stability Analysis with Strain Localization
Nowadays, most slope stability analyses have been performed without considering the effects of shear band width. To improve the estimations, the shear band width was adequately modeled by introducing an internal characteristic length (lc) within the Cosserat continuum framework, and hence the recently developed second-order cone programming optimized Cosserat continuum finite element method (named CosFEM-SOCP) is employed to investigate the effects of shear band width on slope stability. Based on a homogeneous slope example, it can be recognized that neglecting the shear band width for a slope may lead to overly conservative estimations on the FOS of the slope.
