ANCHORAGE TESTS ON STRAIN-GAUGED RESIN BONDED BOLTS

Various aspects of resin bonded rock anchorages are examined using design data based on the results of pull-out tests on specimen anchorages. In such tests the bonded bolt is loaded to failure, this point being determined in terms of deformation or loss of peak load, where it is assumed that the load is evenly distributed as a shear stress along the bonded anchor length. Tests were carried out to study the influence of high bond stresses at the loaded end of the anchor, and also the mechanism of anchorage failure. Results show axial stress and embedment for 750mm and 300mm bonded length bars. A formula is derived for shear stress at the steel/resin interface. /TRRL/
