| 英文摘要 | 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. © 2021, Springer Nature B.V. |
