Abstract: This article summarizes the current status of slope stability research in China, introduces the development process, characteristics, and applicable conditions of slope monitoring methods and equipment, analyzes the methods, early warning models, and application scope of monitoring, early warning and forecasting technology, and various methods of slope reinforcement technology are systematically introduced, and typical complex slope problems are discussed. On the basis of summarizing the existing problems of slope research, the future development trend is prospected from the aspects of in-depth slope theory research, lean slope stability control, intelligent slope monitoring technology, etc. The main direction of future open-pit mine slope research is expounded.
