Abstract
In the reinforcement of slope management measures, the arrangement of anti-slip piles is often used to keep the slope stable, and anti-slip piles, as a typical landslide prevention and control structure, occupy a more important position in landslide management. Relying on a landslide in Gansu Province, this paper carries out numerical simulation research on landslide reinforced by anti-slip piles to study the change rule of the stability coefficient of the landslide under natural, rainfall and earthquake conditions as well as the displacement law under earthquake conditions, and then evaluates the reinforcing effect of anti-slip piles in the management of landslides. The results of the study show that, before the landslide was reinforced by anti-slip piles, the landslide mass was in a stable state and a basically stable state under natural conditions and rainfall conditions, respectively, and the probability of failure was small. Under the earthquake condition, the landslide is in an unstable state and is prone to localized failure, and the displacement of the landslide mass in the X direction is larger; The stability coefficients of the landslide mass under each condition were greatly improved after the stabilization of the landslide by anti-slip piles and the X-direction was limited under the earthquake condition, and the landslide was in a stable state. The effect of anti-slip pile reinforcement is good, and it can provide reference for future anti-slip pile reinforcement slope projects.
