摘要： 边坡的支护型式多种多样，挡土墙、抗滑桩被广泛的应用于边坡治理工程，但二者也存在不同的缺陷，使得单一的支护结构型式难以满足工程的需求，桩墙复合支挡结构作为一种治理边坡的新型结构，综合了挡土墙及抗滑桩的优势，被广泛应用。依托贵州省某高填方边坡工程对桩墙复合支挡结构开展研究，对实际工程进行理论计算，最后运用有限元软件建立了相应的数值模型并加以分析，为类似的工程案例提供参考。

Abstract: Various supporting and retaining structures have been used in the landslide remediations. The engineering practice indicating that the single structure type could not meet the requirements in all projects. As a new retaining structure, the piled composited retaining structures, which combine the advantages of sliding resisting caissons and the conventional retaining walls, have been widely used in the slope stability remediation projects. This paper presents a case history of a high fill slope stability project in Guizhou Province. The finite element model was established, and the results were compared with the design values.

Key words: piled composited retaining structures, high fill slopes, numerical simulations, engineering applications
