Slope failure occurring could generate enormous loss to both human lives and properties, and stabilizing piles are broadly used for slope reinforcement as a significant anti-slip retaining structure. The performance of the stabilizing piles is strongly affected by different locations. Presently, most literature focuses on the location selection of single-row stabilizing piles. This paper introduces a classic slope and makes further stability analysis of the slope reinforced by single- and double-row stabilizing piles in different locations. According to the potential sliding surface, the distribution of the bending moment and the thrust, the results show that the failure modes of the slopes reinforced by single- and double-row stabilizing piles are different. As the single-row piles move towards the top of the slope, the failure mode of the piled slope takes on a “shallow-deep-shallow” trend. Moreover, as the pile location and spacing change, the failure modes stabilized by double-row piles can be divided into five categories which could be classified as shallow and deep sliding, and the thrust ratio increases with the increasing pile spacing. Regarding the safety factor, it can be concluded that the optimal location for single-row stabilizing piles within a slope is the lower-middle part of the slope, and the optimal locations for double-row stabilizing piles are proposed at the lower and lower-middle parts of the slope, respectively. The presented analysis could provide significant insight into the design of slopes stabilized by stabilizing piles.

发生边坡破坏可能会给人类生命和财产造成巨大损失，稳定桩广泛用作边坡加固，作为重要的防滑固定结构。稳定桩的性能受不同位置的强烈影响。目前，大多数文献集中在单排稳定桩的位置选择上。本文介绍了一种经典的边坡，并对在不同位置的单排和双排稳定桩加固的边坡进行了进一步的稳定性分析。根据潜在的滑动面，弯矩和推力的分布，结果表明，单排和双排稳定桩加固的边坡的破坏模式是不同的。随着单排桩向斜坡顶部移动，堆积边坡的破坏模式呈现出“浅深深浅”的趋势。此外，随着桩位置和间距的变化，双排桩稳定的破坏模式可分为五类，可分为浅滑和深滑两种，推力比随桩间距的增大而增大。关于安全系数，可以得出结论，斜坡内单排稳定桩的最佳位置是斜坡的中下部，而双排稳定桩的最佳位置则建议在下部和下部。斜坡的中间部分。提出的分析可以为通过稳定桩稳定的边坡设计提供重要的见识。双排桩稳定的破坏模式可分为浅滑和深滑五类，推力比随桩距的增加而增大。关于安全系数，可以得出结论，斜坡内单排稳定桩的最佳位置是斜坡的中下部，而双排稳定桩的最佳位置则建议在下部和下部。斜坡的中间部分。提出的分析可以为通过稳定桩稳定的边坡设计提供重要的见识。双排桩稳定的破坏模式可分为浅滑和深滑五类，推力比随桩距的增加而增大。关于安全系数，可以得出结论，斜坡内单排稳定桩的最佳位置是斜坡的中下部，而双排稳定桩的最佳位置则建议在下部和下部。斜坡的中间部分。提出的分析可以为通过稳定桩稳定的边坡设计提供重要的见识。可以得出结论，斜坡内单排稳定桩的最佳位置是边坡的中下部，而双排稳定桩的最佳位置则是边坡的中下部。 ， 分别。提出的分析可以为通过稳定桩稳定的边坡设计提供重要的见识。可以得出结论，斜坡内单排稳定桩的最佳位置是边坡的中下部，而双排稳定桩的最佳位置则是边坡的中下部。 ， 分别。提出的分析可以为通过稳定桩稳定的边坡设计提供重要的见识。
