摘要：
The deformation and stability of Dayantang slope are studied with adaptive elasto-viscoplastic finite element method. In the calculation, if local instability happens, the edges of tension yield areas will be simulated with Goodman joint elements, meanwhile the mesh will be adjusted and refined. The results show that the local instability of Dayantang slope will not occur,and the minimum safety factor of the entire slope is about 1.143.
