As a slope retaining structures of micropile unit, the micropiles may bear the axial pressure. The paper analyzes the stability of the compression micropile, and establishes the calculation model with the soil resistance. Then we get the ultimate bearing capacity formula using the ZHANG-Method that the distribution of subgrade resistance is constant. With the help of ANSYS buckling analysis, a finite element numerical model can be established. At last, through an example to make comparison to solutions of theory and numerical simulation, and provide useful conclusions.
