- Abstract
The bedding rock slope often induces landslide and other geological disasters after engineering excavation at the foot of the slope. Generally, anchor cables and anti slide piles are used for prevention and control, but its control effect is usually hard to test. Taking the bedding rock slope after excavation of Jiniu hydropower station as an example, combined with the geological conditions, deformation failure characteristics, monitoring data and other data of the deformation body, the discrete element numerical simulation method was used to analyze the landslide deformation response process and basic failure laws under different working conditions, determine its main inducing factors and formation mechanism, and further test the control effect after treatment in combination with the control plan. The research results show that the landslide is a sliding-tension type landslide mainly induced by the front edge excavation. According to its failure mode and topographical and geological conditions, the landslide is comprehensively consolidated by deep and shallow combined means such as deep anchor cable, middle anchor tendon, shallow anchor bolt and surface shotcrete. Both the numerical simulation results and the actual monitoring data show that the deformation trend is effectively controlled, and the engineering prevention effect is good, which has certain guiding significance for other similar projects.
