摘要大型滑坡治理工程常采用双排抗滑桩，悬臂式双排抗滑桩就是其中常见的一种型式。首先对悬臂式双排抗滑桩的最优状态进行假定，分析双排抗滑桩的力学传递过程。然后运用土拱理论和极限平衡理论，推导前、后排抗滑桩所承受滑坡推力的计算公式，提出滑坡推力的分配计算方法。最后运用该方法对杭金衢高速公路K103滑坡中的悬臂式双排抗滑桩工程进行计算，理论计算结果与监测结果相对比，证明该方法的正确性和适用性。该计算方法可为悬臂式双排桩的设计提供理论依据。在悬臂式双排抗滑桩的设计中，建议首先进行滑坡推力的分配计算，然后再进行结构设计。

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.
