Abstract Double-row anti-sliding piles are often used in large-scale landslides. Cantilever double-row anti-sliding pile is a common type. Firstly，the optimal state of the cantilever double-row piles was assumed，and the mechanical transfer process of the cantilever double-row piles was analyzed. Then，based on the soil arch theory and the limit equilibrium theory，the formulas of landslide thrust loaded on the front and rear row piles were derived，and the method for calculating the distribution of landslide thrust was proposed. Finally，the calculation method was used to calculate the landslide thrust on the cantilever double-row anti-sliding piles of the landslide K103 along Hangzhou―Jinhua―Quzhou expressway. The theoretical results were consistent with the monitoring results. Thus，the correctness and applicability of the method were verified. This calculation method could be useful for the design of cantilever double-row anti-sliding piles. In the design of cantilever double-row anti-sliding piles，it is suggested to calculate the landslide thrust distribution firstly，and then to conduct structure design.

Key words： pile foundations landslide thrust cantilever double-row anti-sliding piles landslide
