STRESZCZENIE
We verify experimentally the recommendations put forward in the International Standards for anchorage in concrete concerning the assessment of the load-carrying capacity of anchors (the pull-out force) embedded in natural rock material. Regarding the predicted extent of surface failure we have shown, in earlier studies, substantial discrepancies between the strength test results for anchorages in the rock mass and the established standard recommendations for anchorages in concrete. As regards the industrial practice and the goals of the reported project, simplified calculation procedures are sought that will facilitate the selection of optimal configurations for the layout of anchor holes, while being computationally effective and applicable in the industry-specific conditions.
