英文摘要	Abstract The stability of deposit slopes against sliding is studied using the limit equilibrium methods in this paper. As a case study, all the results are shown based on deposit slope in front of the dam of A’hai Hydropower Station, China. A calculating strategy to improve the convergence of rigorous Janbu method is proposed using cubic B-spline interpolation smoothing processes of inter-slice moment distribution. The factor of safety calculated by the modified rigorous Janbu method in this paper is consistent with those obtained by other limit equilibrium methods. It has been shown that the deposit slope in front of the dam is stable under natural conditions. The factor of safety of deposit slope stability against sliding is between 0.865 and 1.167 under normal water level conditions, which indicates that local instability of deposit exists. The factor of safety is sensitive to internal friction angle of alluvium under the water-saturated state. Some treatment measures are briefly discussed to improve the stability of the deposit in front of the dam.
