Abstract: This paper presents the case history of the Bizhong landslide in Panzhou area. The geological conditions and characteristics of the landslide are discussed, and the triggering mechanism and stability aspects of the landslide are analyzed. Based on the analysis of the landform and geomorphology, soil and rock characteristics, precipitation conditions and adverse human activities, the results show that the back side of the creeping body pushes the middle and front portion of the soil mass, forms the translation-compression failure mode; On the basis of qualitative evaluation, the factor of safety of the landslide is quantitatively evaluated. The results show that the landslide is basically stable under the natural condition and becomes unstable under the rainstorm condition. The precipitation is the main factor that influences the landslide, and rainfall is the main factor that triggering the landslide.

Key words: Panzhou Bizhong Landslide, Triggering Mechanism, Stability Analysis, Displacement-Compressive Failure Mode
