Slope stability analysis and treatment measures based on FLAC
The slope stability issue of riverbank is addressed through limit equilibrium analysis using Geo-studio software and numerical simulation verification with FLAC.The results indicated that the slope was unstable during heavy rain conditions,with a maximum displacement of 100.0 mm and a maximum shear strain increment of 4.45x10-2.The shear-n plastic zone had been fully penetrated,and the slope landslide mass showed an overall sliding trend.Following reinforcement with double-row anti-slide piles,the stability coefficient of the slope significantly improves compared to its pre-treatment state.The maximum displacement after reinforcement is only 1.8 mm,and both the maximum strain increment value and distribution of shear failure plastic zone in the slope landslide are notably reduced,indicating that it has reached a stable state,This validates the reason-ableness and feasibility of the design scheme,providing valuable reference for similar slope treatment projects.
