Analysis of Influence Factors of Anti-Slide Pile with Prestressed Anchor Cable Based on Bearing and Deformation Characteristics of Pile Body

In order to deeply study the mechanism of prestressed anchor anti-slide pile, an indoor model experimental device was developed, and a finite difference particle flow numerical analysis slope cable pile established based on reinforcement project in mountain road slope. Based force displacement characteristics influence prestress cable, inclination angle width column spacing landslide, height nature filling soil deformation are discussed, some design parameters optimized. Results show that larger smaller body, but excessive stress is not conducive safety body. The optimal tension should be 50–70% designed cable. With increase decreases first then increases, there double row piles, with spacing, front piles gradually change from supporting between sliding body back plum-shaped. When 2.5 times diameter, rear most reasonable. process arching evolution, cohesion effect greater than internal friction angle.
