After analysizing the results of SSRFEM and centrifugal model test, someconclusions are drawn that, the depth of slip surface implies that the Bishopssimplied method cannot indicate the true failure mechanism for the slopes reinforcedwith piles. The rate of safety factors decreases with the pile spacing decreasing, andthe salty factor of the slopes is the largest when the reinforced piles are installed in themiddle of the slopes, regardless of pile head confining conditions, and the deflection,maximum bending moment and shear force in the reinforced piles in the criticalcollapse are the biggest meantime. The fixed and hinged head condition of the pilesresults in smaller bending moment in the piles than that in unrotated and free headcondition, therefore the restrained pile head condition is recommended in the design.

3不同特性与工况下抗滑桩与土体相互作用的数值分析与离心模型试验研究表明：采用简化Bishop法计算得到的滑动面不能反映抗滑桩加固边坡的破坏机理，抗滑桩设置在边坡中部和减小桩间距有利于提高边坡稳定安全系数，而此时抗滑桩在边坡临界破坏时的挠度、最大弯矩和最大剪力相对较大；桩头固定、铰接与桩头自由、平移相比，所加固边坡的整体水平位移及边坡临界破坏时抗滑桩的最大弯矩相对较小，而稳定安全系数则较大，因此在进行抗滑桩设计时应尽量选择桩头固定与铰接的型式，或对桩头进行锚固以改善抗滑桩的受力特性，提高边坡的稳定安全性状。
