By using the finite element software ANSYS and the application of strength reduction method principle,the slope reinforced by different inclined micropiles is analyzed by numerical analysis,the stability coefficient of natural slope,the slope reinforced by vertical micropiles and inclined micropiles are calculated,and then the stability of slope reinforced by inclined micropiles is evaluated.The results show that the stability coefficient of natural slope is 1.04 and the stability coefficient of the slope reinforced by vertical pile is 1.17.Compared with the slope reinforced by vertical pile,the stability coefficient of the slope reinforced by different inclined micropiles are increasing by various extents.When the inclination angle of micropiles increases from 10 degrees to 60 degrees,the stability coefficient of the slope increased from 1.22 to 1.65,the slope stability is improved obviously and this reaches the reinforcement effect of the slope.
