Anti-slide mechanism of anti-slide piles and engineering application of anchor anti-slide piles

The horizontal deformation of a cantilever anti-slide pile or an embeded anti-slide pile is less than that of landslide due to large pile diameter and stiffness, which leads to local cracking of the slope. On the basis of analyzing the stress and deformation of a cantilever anti-slide pile and an embeded anti-slide pile, the anchor anti-slide pile was put forward to reinforce subgrade landslide. As an embeded anti-slide structure, it solved not only the unreasonable stress problem of a cantilever anti-slide pile but also the local cracking problem of the slope. The stress of the anchor anti-slide pile was simulated with FLAC software in subgrade reinforcement engineering.
