Rainfall infiltration is a major cause of slope instability, and many researchers have conducted extensive studies on the mechanism of slope instability under the influence of rainfall infiltration. The design of slope support currently faces several challenges, including a shortage of appropriate design basis, dependence on imprecise, experience-based, or analogy-based designs, and the absence of focused and optimized design methods. Using numerical simulation, this study aimed to find the impact of various anchor reinforcement schemes on slope stability during heavy rainfall. Several anchoring reinforcement schemes have been proposed, the impact of anchoring angle, anchoring distance, anchoring length, and other parameters on the slope’s safety factor has been analyzed and compared, and the optimal solution has been suggested.

摘要

Rainfall infiltration is a major cause of slope instability, and many researchers have conducted extensive studies on the mechanism of slope instability under the influence of rainfall infiltration. The design of slope support currently faces several challenges, including a shortage of appropriate design basis, dependence on imprecise, experience-based, or analogy-based designs, and the absence of focused and optimized design methods. Using numerical simulation, this study aimed to find the impact of various anchor reinforcement schemes on slope stability during heavy rainfall. Several anchoring reinforcement schemes have been proposed, the impact of anchoring angle, anchoring distance, anchoring length, and other parameters on the slope’s safety factor has been analyzed and compared, and the optimal solution has been suggested.
