抗滑桩加固边坡的增强作用与抗滑桩设置位置、桩头条件等密切相关,通过离心模型试验对不同桩位与桩头条件下采用抗滑桩加固边坡的变形破坏特性进行研究。试验表明,设在边坡中部的抗滑桩在边坡破坏前桩头水平位移最大,而在相同的破坏载荷作用下,设在中部的抗滑桩比设在上、下部以及桩头固定比桩头自由时边坡破坏后的位移矢量要小,这表明抗滑桩设边坡中部以及桩头固定对边坡土体的遮挡效果及边坡安全系数的提高最好。
The strengthening effect of the anti-slide piles strengthened slope is closely related to the anti-slide piles’ installation position and the conditions of the pile heads. The deformation and failure characteristics of anti-slide piles reinforced slopes under different pile positions and pile heads are studied by centrifugal model tests. The tests show that the anti-slide piles located in the middle part of the slope have the largest horizontal displacement before the failure of the slope, while under the same failure load, the anti-slide piles located in the middle part are located at the upper part and the lower part, When the pile head is free, the displacement vector after the failure of the slope is small, which shows that the anti-slide pile is located in the middle of the slope and the pile head fixed on the slope soil and the slope safety factor is the best.
