An experimental study of axial load transfer mechanisms of cable bolts using axially split embedment apparatus
The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. The tendon strength can be evaluated by the tensi...

متن کاملInnovative approach to strata reinforcement in coal mines with reference to evaluation cable bolts shear strength
There is an increasing need to determine accurately the strength properties of tendons for an effective ground control on mines and underground structures as well as on modelling simulations. The strength properties of cables, used as cable bolts, have been evaluated mainly by their ultimate tensile strength, as this kind of test can be carried out in the field as well as in the laboratory. Onl...
متن کاملMatching Nuts and Bolts Optimally∗
The nuts and bolts problem is the following : Given a collection of n nuts of distinct sizes and n bolts of distinct sizes such that for each nut there is exactly one matching bolt, find for each nut its corresponding bolt subject to the restriction that we can only compare nuts to bolts. That is we can neither compare nuts to nuts, nor bolts to bolts. This humble restriction on the comparisons...
متن کاملBrane worlds with bolts
We construct a family of (p+3)–dimensional brane worlds in which the brane has one compact extra dimension, the bulk has two extra dimensions, and the bulk closes regularly at codimension two submanifolds known as bolts. The (p + 1)–dimensional low energy spacetime Mlow may be any Einstein space with an arbitrary cosmological constant, the value of the bulk cosmological constant is arbitrary, a...
