Double-row anti-slide piles are one of the common measures for large-scale landslide control, and there are many engineering applications and related research results. However, its bearing mechanism still needs to be further studied, and the relevant design standards have not been formed, which limited the development of cantilever double-row anti-slide piles. In view of this, the research results of the slope treatment mechanism of cantilever double-row anti-slide piles are summarized, the reinforcement mechanism of double-row anti-slide piles and the factors affecting the bearing characteristics of anti-slide piles are reviewed. Three research methods, including theoretical calculation, experimental research and numerical simulation that are commonly used in the study of double-row anti-slide piles reinforced slope and related results, and their advantages and disadvantages are compared and analyzed. Based on the current research status of double-row anti-slide pile reinforced slope, the cutting-edge scientific problems that need to be solved urgently and the focus of future research are concisely pointed out, providing a theoretical basis for the development and improvement of the theory and engineering technology of double-row anti-slide piles slope treatment, and a certain guiding significance for the compilation of relevant specifications and practical engineering.
