Evaluation of Slope Stability at Interface using Thin Soil Material Model in Finite Element Software

Abstract Cases of landslides on clay shale slopes have been an intriguing study in Indonesia. Most the failed due to weathering rock. As studies focused properties shale, several FEM analyses indicated a unique translational type failure between interface and its overburden. However, modeling case was still limited. This aims evaluate landslide using thin-soil model software. The used two conditions, extreme groundwater level conditions. There were iterations shear strength parameters layer conducted. Results that could portray condition at landslide. Compared laboratory results, would fail high degree saturation water infiltration surface. Also, granular overburden with permeability had higher chance than cohesive From this opened path incorporating slope analysis. further are needed other cases synthesize repeatability.
