Experimental Study on the Shear Mechanical Properties of Anchor Cable with C-Shaped Tube

Faced with serious tensile–shear fracturing of anchor bolts and cables in deep roadways, it is great significance to investigate Anchor Cable C-shaped tube (ACC), a combined structure an cable high strength shear resistance. The mechanical properties the ACC are systematically investigated using technical means theoretical analysis double-shear tests. improved equipment for test not only considers initial normal stress but also ensures continuity cable’s axial force transmission while considering influence inclination angle on performance supporting components. research indicates that inhibits occurrence concentration near joint surface improves state cable, transforming its failure mode from tensile failure. Compared has higher capacity, greater stiffness better ductility direction. capacity when perpendicular plane than inclined 80°, linear stress. Two methods were proposed contrast between ACC, including components surface. former evaluate capability latter ability control deformation tests results show average 279 kN increase 34.9%. anchored by 306 25.2%. can effectively improve free section wide application prospects.
