forward on the basis of strength reduction theory and rheological 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......
