A Comparative Study between Polyline and Straight Line Arrangements of Antislide Piles Based on Soil Arching Effect

Considering the limitations of terrain and engineering expenses, antislide piles are sometimes arranged in polylines. Studies show that this arrangement adversely affects the mechanical characteristics of antislide piles. However, there is no in-deep understanding of this issue and the structural de...

description Considering the limitations of terrain and engineering expenses, antislide piles are sometimes arranged in polylines. Studies show that this arrangement adversely affects the mechanical characteristics of antislide piles. However, there is no in-deep understanding of this issue and the structural design and calculation method of this arrangement have not been discussed in relevant standards. Aiming at resolving this shortcoming, the polylines pile arrangement is studied in this article to provide a scientific basis for designing and calculating antislide piles. To this end, the cantilever pile is taken as the research background, and the soil arching effect between piles is taken as the research object. Then the performances of the single-row polyline pile layout and straight line pile layout are analyzed in the Dawanjiang landslide and the results are verified from the aspects of the landslide reinforcement and the influence on the antislide pile structure. The obtained results show that the polyline pile layout is disadvantageous to the safety of the antislide pile structure, and the soil arch between piles under the polyline pile layout condition is not uniform. Meanwhile, it is found that as the polyline pile layout angle increases, the stress concentration appears at the “inflection point.” Under this circumstance, the soil arch between piles is not uniform, and the stress concentration intensifies.
