Abstract: The stability aspect of a high slope near the river bank was evaluated with commercial software SLIDE. The slide plane with the minimum factor of safety is located. This slope is also numerically analyzed with the commercial software FLAC3D under the river scoured as well as the heavy precipitation conditions. The effect of the slope deformation on the adjacent building structure is investigated. The deformation influence line of the slope can be plotted based on the displacement vectors and the plastic zones. The slope stability analysis results demonstrate that the most probable sliding plane is within the fill and silty soils. The river scour has impact on the slope movement and the movement increase under the heavy precipitation conditions and might result in the adverse effect on the adjacent building. The site monitoring results are consistent with the analytical results.
