The snakeskin-inspired pile, by mimicking the frictional anisotropy exhibited by the ventral scales of snakes during movement, demonstrates significant engineering potential at soil-structure interfaces. This paper reviews the latest research progress on snakeskin-inspired piles and anchors, focusing on their performance in pullout resistance and shear strength, particularly under varying soil conditions such as sand and clay. The literature review reveals that the geometric design of bio-inspired scales plays a crucial role in friction resistance and soil disturbance. Different scale parameters exhibit notable frictional differences between cranial and caudal shear directions. Additionally, this paper addresses the limitations of existing studies, including discrepancies between laboratory conditions and real-world applications, as well as stability challenges under long-term dynamic loads. Future research should focus on optimizing scale geometry, validating the adaptability of these designs in complex dynamic environments, and exploring new materials and advanced manufacturing techniques to enhance durability and cost-effectiveness. These efforts provide theoretical support and a research foundation for the future application and design optimization of snakeskin-inspired pile.
