It has been about 50 years since ground anchorages were introduced to Japan. The number of permanent anchors constructed has already reached ab out 100,000 a year. Howeve r, an increasing number of corrupted anchors have been reported recently. If th ere is a problem in the design of anchorages, one of its possible causes is the yet-to-b e-clarified mechanism of the anchors' adhesion to the bedrock, in particular.
In this study, we conducted a detailed examination on the behavior of the anchor body in relation to the pseudo bedrock and examined support mechanism of anchorages. Based on its results, we suggest improvements for the designing standard of the anchorages.
