The double-row anti-slide pile is one of the main measures for treating medium and large-scale landslides. However, the pile–soil interaction mechanism and the influence of the row spacing and the pile spacing on the interaction are not very clear in the process of the load-caused landslide evolution. Based on the interaction model test of the double-row anti-slide pile and the load-caused landslide is carried out by using transparent soil model technology. The research results show that the transparent soil technology has advantages in capturing “wave-type” distribution of the displacement isoline and studying the pile–soil interaction and the soil arching effect in the landslide. The pile–soil interaction process can be divided into three stages, the initial deformation stage, the soil arch stability stage, and the deformation stage of the soil arch. With the increase in the row spacing, the reinforcement effect of the front pile to the rear pile is weakened. With the increase in the pile spacing, the phenomenon of soil flow around piles is more likely to happen. Pile spacing has a significant effect on landslide displacement control. And when the row spacing and the pile spacing are too large, there is no soil arch stability stage in the process of the landslide evolution. The conclusion has specific guiding significance for engineering practice.
