... ABSTRACT: Rock anchors are used to stabilise large scale infrastructures. The literature describes four failure modes of rock anchors: (1) steel tensile failure; (2) anchor-grout interface failure; (3) grout-rock interface failure; and (4) rock mass uplift. In this study full scale field tests...
