Study on Landslide Early Warning of Mayanpo Slope at Xiangjiaba Hydropower Station
The paper has in-depth systematically studied stability and early warning of high engineering high slopes in depth, and established the early early-warning model of slope and the health diagnosis system. The results show that: ① displacement deformation increases with time and decreases with increasing depth. Changes of displacement can be divided into three stages: deformation rapidly increases in the early, and slowly increases in the medium term, and becomes gradually stable in the later; ② by through stability analysis of Mayanpo slope of Mayanpo slope ofby finite element strength reduction FEM, stability coefficient is 1.72; ③ Using using boundary displacement method and taking the equivalent plastic strain region through as a criterion for the early- warning analysis of slope landslide landslide, the paper presents establishes the early-warning monitoring system of slope based on double controlleding indicators of displacement deformation amount and safety factor.
