This paper discusses the experimental and numerical studies of multiple strand clip anchors. Determine the test procedure and give information about the test, such as the deflection of the anchorage and the strain distribution along the peripheral surface of the anchorage. However, the test program does not provide internal information on anchors, such as internal stress - strain distribution, stress concentration and yield percentage. An effective numerical finite element model analysis method is given, which can provide the above intrinsic information. The model includes all kinematic materials that touch non-linear elements and are first calibrated using test data. Finally, the numerical study of the anchorage was completed and its characteristics under different loading conditions were tested. In particular, the use of different aspects of the issue, such as the application of high-strength steel wire and so on
