Research conclusions ： (1) The shear stress in the bonding section is distributed in the light of exponential curve form of the single peak in stead of unevenly distributed form when the anchor is loaded. The recursive control anchor can disperse the concentrated load into several smaller loads on the different bonding sections among the sliding masses to make full use of the formation strength of the free segment. (2) The results of numerical simulation are basically consistent with the results of the qualitative analysis and model test. It shows that the numerical simulation of the anchor action process is feasible, (3) The recursive control anchor can overcome the traditional anchor's shortcoming that the counter - force load is entirely borne by external anchor structure and can reduce the size of external anchor structure effectively. (4) The research results can be applied in the slope reinforcement and quick treatment of the disease.
