摘要
Abstract
The Engineering area of Mengdigou Hydropower Station is characterized by complex geological struc-ture,wide distribution of dangerous rock masses on the slopes of the hub area,and developed altered rock.The excavation slope of the switch station is mainly strong unloading Class Ⅳ rock mass.There are many small faults on the slope,joints,fissures and altered rock belts are randomly distributed,and the local topography is very steep.In this paper,the deformation and failure modes of the switch station slope are analyzed,and the global stability and the stability of the potential sliding block are calculated by using the method of the lower limit of plane limit equilibrium,and the supporting scheme of slope is put forward,which provides an important basis for engineering design and construction.关键词
