The failure of artificial rock slope of cut in macroseismic area always causes enormous damage. From the data of various macroscopic earthquake damages in Tonghai, Zhaotong earthquake areas (Yunnan Provirice) and Haicheng earthquake area (Liaoning Province) and from the point of view of engineering seismogeology, the structure of rock mass, the spatial combinatory relationship between the structure surface of rock mass and the slope orientation, and the effect of seismic intensity on the stability of the slope of cut are discussed in this paper. In addition, some ideas with practical engineering significance are presented for reference.
