常见的抗滑桩支护结构在膨胀土渠坡的加固工程中效果不佳，且投资较大。借鉴锚拉桩的结构形式，设计了一种由抗滑桩、坡面支撑梁和渠底横梁组成的新型组合支护结构，该结构将传统的悬臂式抗滑桩由悬臂结构变为简支结构，提高了结构承载力。工程实例表明，新的支护结构对渠坡坡面变形和渠底回弹变形具有抑制作用，而且相比传统双排抗滑桩支护方案，工程投资显著减小，为膨胀土渠坡支护设计提供了一种新的永久支护形式。

The effect of common anti-slide pile is unsatisfactory in reinforced project of expansive soil slope despite huge in-vestment. By referring to structural form of pull-anchor piles, a new supporting structure composed of anti-slide pile, slope brace beams and canal bottom cross-girder is designed to substitute simply supported type for cantilever type of traditional anti-slide pile so as to improve bearing capacity. The engineering practice shows that the new supporting structure has inhibiting effect on surface deformation of canal slope as well as rebounding deformation of canal bottom, and the project investment of new sup-porting solution is obviously smaller compared with traditional double-row anti-slide pile.
