摘要:
采用传统的不平衡推力法及Janbu（简布）法改进之后对应的部分强度折减法，分别对杨家沱滑坡稳定性进行了分析，对比研究结果可得：经折减后的不平衡推力法和简布法计算出的推力均随临界状态点位置变化呈现增长趋势，当最后一个条块达到临界状态时，此时算出的稳定系数则是滑坡的整体稳定性系数。计算出简布法的强度折减稳定系数比不平衡推力法大，同样可界定滑坡的稳定状态，演示了滑坡的逐步渐进破坏过程。
Abstract:
In this paper, the stability of Yangjiatuo landslide is analyzed by partial strength reduction method, including unbalanced thrust method and Janbu method. The results show that the unbalanced thrust increases with the position of the critical state point. When the last block reaches the critical state, the stability coefficient calculated is the landslide. The overall stability coefficient is calculated, and the strength reduction stability coefficient of the simplified method is larger than that of the unbalanced thrust method. At the same time, the stability of the landslide can be calculated, which can also be used to stabilize the stability of the landslide. It shows that the landslide is progressively destroyed. The strength reduction method of some slices can approximately reflect the destroying trend of the landslide.
