摘要
简述了2种基于极限平衡理论分析土坡稳定性的方法,利用SLOPE/W软件对某水库土坝边坡进行了稳定性分析,建立了坝坡稳定性的分析模型,研究了在各种库水位情况下坝坡的安全系数随土的强度参数的变化规律,以及强度参数对坝坡最危险滑弧形状和圆心位置的影响。并对Bishop法和太沙基法两种计算方法在土坡稳定分析中存在的差异进行了讨论。
In this paper,two kinds of methods for soil slope stabih＇ty analysis based on limit equilibrium theory are presented, SLOPE/W soft- ware is used to analyze a reservoir earth dam slope stability, the analysis model is established, the relationship between the dam slope safety factor and the reservoir water level as well as the influence of strength parameters on the dam slope most dangerous slip curve shape and its center location are studied. The difference in soil slope stability analysis between Bishop method and Terzaghi method is also discussed in the paper.
