加筋土挡墙是一种利用土工合成材料与填料共同作用稳定路堤边坡的一种挡护结构，具有占地少、结构稳定、形式美观等特点。但是这种结构对填料要求严格，填料一般应为均质的土质填料，对千枚岩填料适应性较差。通过徽杭高速公路第十六合同段的施工，总结了千枚岩地区加筋土挡墙的施工工艺，对挡墙稳定性进行了检算，并提出有关结论。

Reinforced earth retaining walls are a kind of retaining structures consisting of geosynthetics and filling materials that are constructed for the stabilization of the embankment side slopes. Reinforced earth retaining walls have such features as small land occupation, stable structure and good appearance. However, reinforced earth retaining walls have strict requirements for the filling materials. In normal cases, the filling materials should be homogeneous soils. Phyllite filling materials are difficult to be used as the filling materials for reinforced earth retaining walls. On basis of the construction of No. 16 contract section of HuiHang highway, the author summarizes the construction techniques for the construction of reinforced earth retaining walls in phyllite area, makes checking calculation on the stability of the retaining walls and draws some conclusions.
