Abstract：In the flexible protection systems，the load applied on the cable anchor had a contain angle with the axial direction，but the axial pullout capacity was the only design principles currently which was not reflected the actual working conditions. The mechanical performance of the cable anchor with different bolt hole diameters and testing load directions were investigated. The results show that the anchor performance was improved and the displacement was decreased by increasing the bolt hole diameter or increasing the included angle between the anchor horizontal direction and the oblique load direction. In addition，the pullout capacity was enhanced with the heart-shaped ring consolidation when the pullout capacity of the cable anchor determined by the limited force. Finally，the way to design the cable anchor in the flexible protection systems was also presented.
