Anti-slide pile structure development: New design concept and novel structure

The anti-slide pile is one of the most used measures in landslide control globally. Following its application, various structures have been developed. In this paper, we analyze structure development process and extract two paths. One path aimed at improving applicability. second starts from an in-depth study pile–soil interactions. However, these paths share a single design concept: provides direct resistance to maintain stability, that is, body are thought be confrontational sides. We here propose developing utilizing design. Accordingly, confrontation relationship between can changed while shifting away view only hazard. On basis, also novel structure: An arm-stretching-type pile. simulation verification results show works well realizing proposed concept. Compared with commonly wholly buried pile, safety factor controlled by improved 43.56%. This promotes concept existing slide–resist mode slide–self-stabilize–resist compound mode.
