The anti-sliding structure of the side slope usually adopts anti-sliding piles, and the pile has the effect on the sliding mass, namely, the resistance (anchoring force) of a stable stratum below a sliding surface of the anti-sliding pile inserted into the pile is utilized to balance the thrust of the sliding mass, so that the stability of the sliding mass is improved. When the sliding body slides downwards, the sliding body is resisted by the anti-slide pile, so that the sliding body in front of the anti-slide pile reaches a stable state. Because the side slope is generally in a position which is difficult to reach by traffic, the anti-slide piles and the anti-slide walls for reinforcing the side slope are relatively large in size and difficult to transport, in addition, after rainfall, rainwater permeates into the soil body of the side slope, the dead weight of the side slope is increased, the shear strength is reduced, and the side slope is easy to generate.
