“…Since then, some studies have been further promoted for the stability evaluation of landslides under unsaturated conditions and vibration (Wang et al, 2019;Nie et al, 2020). In conclusion, the instability mode of rock under anti-slide pile reinforcement is closely related to groundwater (Zhang et al, 2020;Liu et al, 2020b;Wang et al, 2020a), rock and rock parameters (He et al, 2020;Zhang et al, 2021), and external load (Huang et al, 2020). However, most of these studies ignore the influence of the rock mass in front of an anti-slide pile.…”

To study the stability evaluation method and failure mode of reserved rock masses, the Yueyang landslide project was taken as the research object. First, based on the limit equilibrium method and elastic mechanics, the formulas for calculating the stability of a reserved rock mass were analyzed. Second, the failure modes of the reserved rock mass were tested by the experiment model. The results show that the failure modes of the reserved rock mass can be divided into three modes: upward sliding failure, downward sliding failure and tensile crack failure, which are mainly related to the strength and width of the reserved rock mass. Therefore, it is unreasonable to regard a reserved rock mass as a unified failure form in the design of anti-slide pile reinforcement. In addition, although both moderate-strength and strong-strength reserved rock masses exhibit tensile crack failure, moderate-strength rock masses under triangular loading are prone to tension-sliding failure, while strong-strength rock masses under parabolic loading are prone to tension-overturning failure. Finally, the displacement and stress monitoring results in the experiment are basically consistent with the theoretical analysis, indicating that the theoretical analysis results have high reliability.
