Research on the Influence of Weak Interlayer in Open-Pit Slope on Stability

The weak interlayer in the slope meets with water threatening overall stability of slope. Sequestration location layer has an impact on Based this, taking south-side Fushun West Open-Pit Mine as background, limit equilibrium method was used to study influence different depths and dip angles interlayers factor-of-safety sliding mode After analyzing effect, a bottom friction experiment conducted verify theoretical results. research results show that, buried depth becomes larger angle smaller, safety factor increases. Dip both affect This can provide reference for mechanism multi-weak-layer slopes.
