Abstract Research purposes ： In the complex construction environment，for the shallow depth of the anti - sliding pile anchoring section in the landslide hazard， it is used to add the vertical pre - stressed anchoring cable to enhance the capacity of the pile. Based on the K 60 landslide of Songjian highway，this paper analyzed the characteristics of anti - sliding pile with vertical pre - stressed anchoring cable，and established the calculation and analysis model of its anti - slipping property，and combined numerical analysis method to research its effect on the slope stability. Research conclusions ：( 1) Through numerical analysis and two years displacement monitoring，it was proved that the effect of the frame pile with vertical pre - stressed anchoring cable in the K60 landslide control engineering was well. For adding vertical pre - stressed anchor cable in the anti - sliding pile，it not only increased the bending capacity of the pile，but also enhanced the anti - slip ability of the pile. Especially，it had a significant advantage for the anti - sliding pile of the more shallow embedded rock. (3) Compared with the traditional anti - sliding pile， adding the vertical pre - stressed anchor cable in anti - sliding pile saved the material，reduced the time of landslide control，and also reduced the risk of safety accident of slope. (4) The research results can provide references for the railway or highway landslide engineering in emergency rescue.
