Abstract
Distribution of both axial force and skin friction should be investigated in order to estimate pull-out capacity of ground anchors. Numerical method of computing load-transfer characteristics of the ground anchors, however, has not been specified and studies on this area are not sufficient. This study suggested the numerical method of simulating the characteristics of axial force and skin friction distribution against the tension type ground anchors. Also, debonding behaviors of skin friction and axial force were calculated by the suggested numerical method as a function of load levels. As a result of the review, it is confirmed that the distributions of axial force and skin friction by the suggested numerical method are relatively similar to those of field test results.
