Abstract | Various testing methods have been proposed and conducted on cable bolt pull out in the last century. Large and small scale tests have both provided valuable information about the behaviour of the cable bolts. This study compares large scale and small scale pull out experiments with similar cables, bonding agents (grout and resin), and loading paths (monotonic and cyclic) to juxtapose the unique characteristics of each test. The results suggested that small scale tests in grout tend to have lower repeatability compared to large scale test while large scale test typically provide a stiffer behaviour with higher initial peak loads. In cyclic loading, large scale testing tended to have most of their cycles in the first 5 mm whereas small scale test loading and unloading cycles were more spread. In resin cases, bulbed cables had similar behaviour whereas the unbulbed cables had various load values suggesting the presence of bulbs overshadows other characteristics. |
