Couple analysis on strength reduction theory and rheological mechanism for slope stability
Considering the rheological properties of rock and soil body, and exploiting the merit of strength reduction technique, a theory of couple analysis is brought forward on the basis of strength reduction theory and rheologicai properties. Then, the concept and the calculation procedure of the safety factor are established at different time. Making use of finite element software ANSYS, the most dangerous sliding surface of the slope can be obtained through the strength reduction technique. According to the dynamic safety factor based on rheological mechanism, a good forecasting could be presented to prevent and cure the landslide. The result shows that the couple analysis reveals the process of the slope failure with the time and the important influence on the long-term stability due to the rheological parameters.
