摘要
Taking a strong deformed and weathered phyllite slate slope in the south of Anhui Province as an example,through investigation into geology conditions and slope rock mass structure type,this paper analyzed and evaluated the slope deformation features and stability.The results indicated that the slope deformation was controlled by the soft rock mass(compressive rupture zone) in the slope,and the shear stress concentration can cause the slope to slide along circular-arc surface.The paper evaluated the slope stability quantitatively and put forward reasonable supporting schemes to reduce possibility of geologic hazard.
