Abstract: Double-row piles are often used to the large-scale landslide. The anchor double-row piles and the frame double-row piles are the two common types. Based on the finite element program ANSYS, finite element models of the two types double-row piles are established separately. Compared the internal force distribution of anchor double-row piles with frame double-row piles, it is found that the frame double-row piles could be better able to play anti-slide effect. For the anchor double-row piles, the difference of internal force distribution between the front and back row piles is very obvious. For the frame double-row piles, the difference is very small. Taking two engineering cases, an anchor double-row piles and a frame double-row piles for examples, through monitoring and analyzing the stresses and displacements of the piles, it is shown that the results are consistent with the finite element analysis. So we suggest using the frame double-row piles in the design

Key words: anchor double-row piles, frame double-row piles, landslide, monitoring
