Stability and reinforcement analysis of rock slope based on elasto-plastic finite element methodLIU Yao-ru(刘耀儒)1, WU Zhe-shu(武哲书)1, CHANG Qiang(常强)1, LI Bo(李波)2, YANG Qiang(杨强)1(1. State Key... limit equilibrium method (RBLEM) and finite element method (FEM) are two widely used approaches for rock slope’s stability analysis currently. RBLEM introduced plethoric assumptions; while traditional......
J. Cent. South Univ. (2020) 27: 1965-1980 DOI: https://doi.org/10.1007/s11771-020-4423-x Stability analysis method of geogrid reinforced expansive soil slopes and its engineering application ZHANG...: The traditional stability analysis method of geogrid reinforced slopes does not consider the effect of lateral swelling, so it is not applicable to reinforced expansive soil slopes. This paper reports a new......
of anisotropy on soil shear strength. In addition, increasing the angularity of grains increases the anisotropy effect in the sample. The stability of a sandy slope was also examined by considering the anisotropy..., the critical slip surface in the most slopes is the same in isotropic and anisotropic conditions.Key words:anisotropy; artificial neural network; sand; principal stress rotation; slope stability......
