Abstract: According to the investigation on geological condition in the north region of China's Shuichang iron mine, this paper analyzes basic features and reasons of the landslide, and suggests that the slope be stabilized by cutting slope and anchorage. A contrast analysis of slope stability is made between unreinforced and reinforced slopes by using FLAC Software. The results show that there is a contradiction between conservatism and unstability in the original slope design, and taking a reasonable reinforcement measure is the key to solve this problem. It is verified that the reinforcment is a very effective measure for this kind of unstable slope.
