Paper presented at the 50th U.S. Rock Mechanics/Geomechanics Symposium, June 26–29, 2016
Paper Number: ARMA-2016-613
... Abstract: Three new methods for identifying axial forces in ground anchor or rock bolt are presented. Unlike in traditional methods that rely on the use of an electronic device, such as strain gauges or load cells, these new methods do not use electronic devices for reading data, but instead...

... elements. The simulation results show that the proposed rock bolt models can predict the shear forces and axial loading along the rock bolts. For the rock bolts observed in this study, the max axial force was within the design limit of the bolts, thus the support design was shown to be acceptable. 1...
