Abstract: Based on the analysis and numerical simulation of ancient landslide revivification, an effective reinforcement measure of micro anti-slide piles combined with pressure grouting, unloading soil and pressing the slope toe was adopted to ensure the road and the cutting slope against slippery. With a practical example, the mechanical analysis and numerical simulation of a micro anti-slide piles are carried out and the result shows that the maximum axial force takes place in the middle and the maximum shear stress is in the 1/3-2/5 height of the pile.
