the importance of researching the interaction between anchorage and ground is discussed. Based on theoretical analysis
the process of the relative-slip between soil and anchorage is composed of three phases; and the mechanism of each phase is explained respectively. And then
the distribution of shear stress in each phase and the distribution of tangential displacement of the interface are presented. After that
a model test of anchorage is carried out with the geometrical scale of 1:100. By analyzing the test results
the propositions in theoretical analysis are performed.
