Deep roadway deformation due to soft rock, rock dip, and horizontal tectonic stress is uneven asymmetrical primarily in large loose zones. Traditional anchor support influenced by the yield strength shear of anchors has a limited prestress capacity or resistance. When roof laminated when passes through layered interfaces, interlayer sliding commonly occurs, which can easily lead cables being sh...

Based on the phenomenon of serious tensile-shear failure bolts and cables, domestic foreign scholars’ research mechanical properties cables has gradually changed from pure tensile to performance. To reduce long-term bolt cable breakage accidents in deep soft rock tunnels coal mines, we independently developed a new type support material—anchor with C-shaped tube corresponding test system. The s...

Abstract Using the spatial structure of external staggered split-level panel layout, a combined support technology for adjacent roadways was developed and analyzed rock bolt anchor cable mechanism. The influence side parameters on mechanical properties anchorage body stress distribution lateral coal were revealed using FLAC 3D software. optimal bolts cables subsequently determined, effect gob-s...

For the failure mechanism of anchor cable lags behind practice demand for theoretical models, Abaqus technique was used to analyze anchoring performances grouted under conditions free and non-free rotating. The tension-torsion coupling characteristics progressive anchorage segment were studied during pull-out test. torsion response internal horizontal vertical strain changes in concrete also an...

Cable termination faults are problematic in electrical networks almost always. Technology has solved problems somewhat, but there are many annual reports about damaged cable terminations. For analyzing the problems, faults in two regional electricity companies are studied. At first step, damaged cable terminations are analyzed statistically and grouped according to their problems. Then, some of...

In this study, nonlinear vibration of a composite cable is investigated by considering nonlinear stress-strain relations. The composite cable is composed of an aluminum wire as reinforcement and a rubber coating as matrix. The nonlinear governing equations of motion are derived about to an initial curve and based on the fundamentals of continuum mechanics and the nonlinear Green-Lagrangian stra...

We described a new surgical procedure of extra-articular stabilization of cranial cruciate ligament (CCL) deficient stifle using nylon cable tie (NCT) anchored in a new tibial anchor point. Lateral fabellotibial tension band (LFTB) stabilization procedure was described in 10 mixed breed dogs. The degree of lameness was scored and complete physical examination of each dog was performed. Radiogra...
