提出了一种单排桩加固边坡的设计方法。现有的方法是基于塑性理论的基础上，用于寻找桩的横向力的临界面以上的部分。假设该力的一部分被动员起来抵抗斜坡的运动。在此基础上，将摩擦圆法推广到稳定性分析中，引入了反力的作用。因此，一个新的稳定性数，包括桩反应被用来确定修改的临界面和安全系数的加固边坡。最后，提出了一个程序，以实现最佳的设计解决方案，提供了一个理想的安全系数的斜坡/桩系统。
A methodology is proposed for the design of slopes reinforced with a single row of piles. An existing method which is based on the theory of plasticity is used to find the lateral forces acting on the pile section above the critical surface. A portion of that force is assumed to be mobilized against the movement of the slope. Then, the friction circle method is extended to incorporate the reaction force in the stability analysis. Thus a new stability number that includes the pile reaction is used to determine the modified critical surface and safety factor of the reinforced slope. Finally, a procedure is proposed to achieve an optimum design solution which provides a desirable factor of safety for the slope/pile system.
