Potvin, J. Carter, A. Dyskin & R. Jeffrey %C Perth %8 16-19 September %B SHIRMS 2008: Proceedings of the First Southern Hemisphere International Rock Mechanics Symposium %X Magnetic anisotropy sensor is used for non-destructive measurement of stresses applied to a nut which is part of the head part on a PS-anchor usually used for stabilising rock mass in large scale underground caverns. Since the stresses in the nut reflect the level of axial force in the anchor, the results of the stress measurement can be used indirectly to estimate the current axial forces of PS-anchors in a non-destructive manner. %1 Perth %I Australian Centre for Geomechanics %U https://papers.acg.uwa.edu.au/p/808_02_Akutagawa/ %R 10.36487/ACG_repo/808_02
