A Sensitivity Analysis of the Anisotropy of Hydraulic Conductivity to the Seepage, Deformation and Stability of Anti-dipping Layered Rock Slopes: A Case Study of the Pulang Area in Southwestern China

Abstract In this paper, in order to study the influence of anisotropy ratios and directions on seepage, deformations stability anti-dipping layered rock slopes, Geo-studio software was used for numerical analysis carbonaceous slate slopes unsaturated fluid–solid coupling, theory Pulang area. The results showed that maximum surface water content gradually decreased with increases conductivity ratio decreases angle slopes. addition, rainfall infiltration depths middle sections were observed be most affected by dip angles formations. Meanwhile, bottom least regard it found layer should considered deformation analyses. When seepage an slope isotropic, safety factors often overestimated. As planes increases, will decrease. This provided a feasible scheme evaluating southwest China’s
