Control Effect of Two Types of Retaining Walls Combined with Anti-slide Tie

Based on the landslide control project of a cableway base in Yanqing District of Beijing, the prevention and treatment effects of vertical retaining walls and inclined retaining walls combined with anti-slide tie were analyzed through modeling. The results show that for self-balancing retaining wall treatment plan, in the condition of certain length of the anti-slide tie and certain height of the retaining wall, when the top of the slope is a natural side slope and the external load is relatively small, the prevention effect of the inclined retaining wall combined with the anti-slide tie is better; when there is a large external load on the top of the slope,the prevention effect of vertical retaining wall + anti-slide tie balanced retaining wall is better. Through the comparative analysis of two self-balancing retaining walls, the treatment measure of vertical retaining wall + anti-slide tie was finally adopted. The supporting structure is currently operating well and the slope is stable, which has certain reference value for similar slope projects.
