"Axial response of resin-encapsulated cable bolts in monotonic and cycl" by Ashkan Rastegarmanesh, Ali Mirzaghorbanali et al.
The ease of use and the design flexibility of cable bolts have made them a popular choice for rock support. Cable bolts can be encapsulated with cementitious grout or resin. There is a need to better understand the impact of resins on the behaviour of cable bolts under varying load and stress regimes over their long service life. This study reports on 18 large-scale resin pull-out tests. The testing apparatus minimised the rotational movement of the cable at the exit point by using a fully grouted anchor tube. Six cable bolts, ranging from 50 to 100 tonnes in capacity, anchored using a fast-cu...
