Rainfall is one of the most important factors affecting slope stability. This study employed multi-source monitoring devices to observe displacements in real time under rainfall infiltration and performed numerical simulations investigate effects different conditions anti-slip pile configurations on Specifically, operations were conducted high steep slopes along Yunmao Expressway. Real-time data deformation, rainfall, displacement at tops piles collected analyzed, using Geo Studio finite-element software. The findings indicated that abrupt deformation occurs once a threshold amount surpassed sustained over specific duration. Slope decreased with increasing depth above potential slip fracture surface, more rapid reduction rates observed reinforced piles. For equivalent amounts, short-duration, intense rainfalls led decrease safety factor, which also recovered rapidly ceased, contrast long-duration, mild rainfalls. presence location significantly influenced stability; therefore, project implementation should carefully consider such as cost duration for optimal decision making.
