摘　　要：预应力锚索抗滑桩因其结构受力合理、材料利用率高特点而在治理公路滑坡中得到工程界的重视,但因其设计和施工较复杂,治理效果还有待更多的工程验证。以广西某公路边坡采用该支挡结构进行治理为例,根据工程的地质情况,在确定抗滑桩参数的情况下以位移协调法对锚索进行设计计算,并对预应力锚索抗滑桩的施工要点进行了分析。根据后期监测结果表明,此滑坡治理效果良好。The piles with pre-stressed anchor cables is a new retaining structure to remediate the highway slopes, which is of the characteristics of well-mechanicals and the high effectiveness of materials and more economical, has been paid much attention. Meanwhile, the design and effect of the remaining structure to remediate a slope shall be proved with projects by and by. The reinforced mechanisms and deformation of the the piles with pre-stressed anchor cables system are analyzed in the paper, the internal forces of the piles with pre-stressed anchor cables system are researched on the base of the models, one of which is the bond length of piles fixed and the other hinged. An example is given in the last, which shows that the the piles with pre-stressed anchor cables to remediate the highway slopes is predominant.
