Double-row stabilizing piles are employed commonly to stabilize large-scale landslides. The key in the design and calculation of practical engineering is to simply and reasonably determine thrust on the front and rear piles. The rock or soil mass in front of loading section of a pile is considered as the Winkler foundation. Using the elastic foundation beam model and fully considering the deformation continuity between loading segment and anchorage segment of the pile

slope resistance on the loading segment of the rear pile can be determined by iterative algorithm. Then

the thrust on the loading segment of the front pile can be figured out using transfer coefficient method for potential slide mass between the front and rear piles. The relative theoretical formulas are given. To verify the rationality of the proposed method

a laboratory model test is conducted. The results are acceptable. For a large-scale landslide example

design slide thrust on a rear or front pile is figured out in detail respectively. The proposed method can provide a reference for the simplified design of practical projects.
