英文摘要	Slope stability is a very important issue in civil engineering; it is especially true of loess slope for its specific regional characteristics. Intact loess was drawn sample from the second, third and fourth terrace in Lanzhou area and the samples were tested in terms of their physical characteristics, such as grain composition, the content of water soluble salt and calcium carbonate and organic compounds. In addition, mechanical properties of c and φ were also examined. The results of the present study show that loess slopes in high terrace are more stable than those of low terrace. According to geomorphologic features, terrace types, physical characteristics, mechanical properties of undisturbed loess, and the results of the slope stability examination, loess slope stability is divided into three kinds: unstable, stable and extremely stable. This classification, on one hand, reflects the engineering geological characteristics of slopes; on the other hand, it helps judge the loess slope stability quickly.
