【摘    要】：针对传统双排桩挡土墙顶部连梁不能满足道路横向较大高差需求的问题，以实际工程为例，设计了一种用于河岸护坡的新型双排桩挡土墙，将悬臂式挡墙和双排桩挡墙结合，能够满足墙顶高差变化的需求；通过线弹性基床系数法（m法）和有限元法的对比，验证了m法对该挡土墙有效性。

【Abstract】：In view of the problem that the top coupling beam of traditional double-row pile retaining wall can not meet the demand of large horizontal height difference of road， based on actual projrct， the paper designes a new type of double-row pile retaining wall for river bank slope protection. This type of retaining wall combines the cantilever retaining wall with the double-row pile retaining wall， which can realize the demand of the change of the top height difference. The effectiveness of M method for this type of retaining wall are tested by comparing M method and finite element method.

【Key words】：double row pile; retaining wall; M method; slope support
