The creep problem could occur in both the anchor and the grout–soil interface under long-term load. For grouted anchors in laterite, it was observed in the above physical model test results that the interface shear creep displacement is dominant compared with the tensile creep deformation of the anchor. For instance, under the load of 5.15 kN, the grout–soil interface displacement reached 3.74 mm, while the tensile deformation of the anchor was only about 0.03 mm. The reason for this phenomenon
