Analysis of Influence of Design Parameters of Anti Slide Pile on Slope Stability

In order to study the influence of design parameters of anti slide pile on slope stability, taking a slope as an example, the pile length (anchorage depth), section length, section width and pile spacing of anti slide pile are changed based on FLAC3D, and the influence of these design parameters on slope stability is analyzed. The results show that the safety factor increases with the increase of pile length (anchorage depth), section length and section width, and the increasing trend gradually slows down; The influence of section width on safety factor is more obvious than that of section length. Therefore, in order to increase the safety of the slope, the method of increasing the section width is more economical and effective than the method of increasing the section length. The safety factor increases with the decrease of pile spacing, and the variation range gradually decreases. However, the increase of pile length (anchoring depth), section length, section width, and the reduction of pile spacing mean more project investment and greater construction difficulty. Therefore, when using anti slide piles to reinforce the slope, comprehensive consideration should be given. It provides a certain technical support for the design of anti slide pile.
