Abstract:
Taking the Guizhoulaocheng landslide on the left side of the Three Gorges Reservoir as an example, the relation between the intact c0,φ0and the driving forces, the relation between the intact c0,φ0and the treatment design, the saturated csat,φsatand the driving forces, the saturated csat,φsatand the treatment design are analyzed by the methods of Janbu Slices and driving force transfer. After the analysis and comparison of the computing results, it is suggested that influence of theφ value on the safety factor and the driving forces is much apparent than that of c value, andφ value is the most critical factor to ensure the safety and investment of the slide- controlling engineering. Therefore, it is significant to choose a reasonableφ value in the stability analysis and the controlling design of landslides.
