Abstract
Currently, tension ground anchors are divided into temporary and permanent based on their purpose and period of use, and their performance evaluations are presented separately. Therefore, applying the current performance evaluation's upper and lower limits to practice seems reasonable. However, because compression ground anchors have been mainly used as permanent, performance evaluation corresponding to permanent is conducted without distinction between temporary and permanent. This evaluation is a strict standard for ground anchors used as temporary, including the removal type. Because of examining the existing performance evaluation for the compression ground anchor, the lower limit can be applied without distinguishing between the temporary and permanent. However, the upper limit should be presented separately for the temporary and permanent. In applying the upper limit, it is necessary to adjust the upper limit of the anchor considering the anchored ground condition (rock or soil), the period of use, and particularly whether the load-displacement curve maintains the elastic state.
