Abstract: The new TC-anchor has excellent anchoring performance and has obvious advantages in anti-floating engineering, gradually gaining widespread application. However, the load transfer mechanism of this type of anchor is not yet clearly understood. In light of this, a study on the load transfer mechanism of TC-anchor was conducted based on field experiments using the finite difference method. The study provided a preliminary analysis of the distribution patterns of axial tension in the rebar, axial stress in the grouting material, and shear stress at the grout-soil interface. Furthermore, the collaborative load-bearing behavior between the compression anchorage segment and the tension anchorage segment was explored. The results indicate that the axial tension in the rebar of the TC-anchor remains constant in the compression anchorage segment but significantly decreases after transferring to the tension anchorage segment. The axial stress in the grouting material is relatively uniform along the cross-section and increases with the applied load. In the compression anchorage segment, the grouting material experiences compression, with the compressive stress decreasing towards the head, and the maximum axial compressive stress significantly lower than that of a pressure-type anchor. In the tension anchorage segment, the grouting material experiences tension, with the maximum tensile stress occurring in the middle and decreasing towards both sides, significantly lower than that of a tension-type anchor. Optimizing the tension-compression length ratio can further reduce the axial tensile stress in the grouting material of the tension anchorage segment. The shear stress at the grout-soil interface of the TC-anchor is highest at the load-bearing body and decreases towards both sides. Compared to tension-type and pressure-type anchor under the same tension, the TC-anchor exhibits significantly reduced shear stress at the grout-soil interface, weakened stress concentration, and a more uniform distribution. During failure, the tension bearing coefficient of the TC-anchor is slightly lower than the tension length coefficient. The ultimate pull-out capacity during collaborative failure of the compression anchorage segment and the tension anchorage segment is higher than that of non-collaborative failure.
