摘　　要：以8 m高加筋陡坡设计为例,介绍了复合加筋土结构形式和单元组成。利用极限平衡条分法和有限元技术分别分析了两种方案的安全稳定性和变形特征,得出了复合加筋土结构与传统加筋土结构相比,性能等效、造价更经济的结论。该结构在温福铁路DK246+300^+360右侧滑坡治理工程中的首次成功应用证实,结构稳定、施工简便,墙体美观。Taking the design of 8m high reinforced steep slope for example,the structural style and composition of composite reinforced soil are introduced in this paper.The stability and deformation characteristics of composite reinforced soil are separately analyzed using ultimate equilibrium slice method and finite element method.It is concluded that composite reinforced soil structure is cheaper with equivalent performance compared with traditional reinforced soil structure.This reinforced structure has been successfully applied in landslide control engineering in right side of DK246＋300~＋360 section of Wenzhou-Fuzhou Railway for the first time,which proves stability,easy construction and beautiful appearance.
