长期以来边坡稳定性分析多采用的是极限状态理论,近来一种新的稳定性分析方法(边坡渐进破坏稳定性分析法)被提出,以向家坡边坡治理为实例,分别研究了传统的不平衡推力法和边坡渐进破坏稳定性分析法中的主推力法在治理中的应用。传统的不平衡推力法只能描述前阶段的破坏过程,而主推力法可以描述滑坡的破坏全过程。研究结果表明:主推力法和不平衡推力法能够应用于工程实践,其中,主推力法更能描述边坡的渐进演化破坏特征。 For a long time, the limit state theory is mostly used in slope stability analysis. Recently, a new stability analysis method (slope progressive failure stability analysis method) has been proposed. Taking slope treatment of Jiajiapo slope as an example, The Application of the Main Thrust Method in the Management of the Traditional Unbalanced Thrust Method and the Progressive Destructive Stability Analysis Method of the Slope. The traditional imbalance thrust method can only describe the destruction process of the previous stage, while the main thrust method can describe the whole process of landslide destruction. The results show that the main thrust method and the unbalanced thrust method can be applied to engineering practice. Among them, the main thrust method can better describe the gradual evolution and failure characteristics of the slope.
