Abstract: Landslide is one of the most common geological hazards in China. After nearly one hundred years of research by many scholars, the theory of slope stability calculation and evaluation, safety prevention and control measures and prediction theory have made qualitative leap and improvements. The relevant design and construction codes are relatively comprehensive, and the relevant limit in slope stability evaluation is also relatively high. Balanced calculation theory, geographic information system, numerical simulation and other methods are improving day by day, which fully and systematically guarantee the safety of various large-scale construction projects. However, due to the level of knowledge of the times and the special material responsible for geological structures and engineering geological components, the complexity of spatial variability cannot completely solve the current work. In this paper, the shortcomings of slope stability evaluation, the future development direction and the problems to be solved are analyzed and discussed.
