摘要：
In order to study deformation and stability of soft rock slope in excavation process, the deformation, plastic area distribution, and the change of safety factor of example slope based on FLAC3D software were studied in this paper. Results show that: (1) the vertical and horizontal displacement of slope gradually increase with excavation; (2) in the process of slope excavation, tension plastic zone occurs in slope surface, and shear plastic zone with connected properties gradually forms internally; (3) based on the strength reduction method and limit equilibrium method calculation, the safety factor of slope gradually reduces with excavation, and adopting the construction form of excavation with supporting meantime is very necessary.
