  • For the bedrock-talus landslides, we used the Flac3D software to discuss the influence of the factors such as the embedded depth, sectional dimension and elastic modulus of the rear-piles on the thrust of the landslide behind the double-row piles, and finally give some practical suggestions for the design of the double-row piles. The analysis showed that the above three factors do not change the thrust distribution pattern on the fore and rear piles. The thrust behind the rear-piles decrease linearly with the increase of the embedded depth of the pile top while the thrust behind the fore-piles increase slightly. The sectional dimension of the rear-piles have great influence on the thrust of themselves but little influence on the thrust of the fore-piles. The elastic modulus of the rear-piles have little influence on the thrust of themselves and the fore-piles.
