Finite element analysis software was used for numerical simulation calculation and small scale model test was made in laboratory. Under step static loading conditions, the slope of 1 : 1.5 ratio, two - way geogrid reinforced layers and four kind of reinforced layer; zero layer, one layer, three layer, four layer are studied in this paper. The performance of embankment is simulated under two kinds of conditions: reinforcement and nn reinforcement. By changing the reinforced layers N and the distance h from top surface of reinforced layer to the bottom surface of the foundation, the effect of performance change of reinforced embankment is also studied. The best scheme of reinforced embankment is put forward. Based on the calculation and test results, the stability of embankment effected by reinforcement structure is discussed in this paper.%利用有限元分析软件进行数值模拟计算和室内小比例尺模型试验,在静力分步加载条件下研究了边坡坡比1∶1.5、双向土工格栅以及四种加筋层数:零层、一层、三层、四层,模拟路堤在加筋与不加筋情况下的性能；通过改变加筋层数N和加筋层顶面距基础底面距离h二个参数,研究了加筋路堤性能变化的效果,提出了对于路堤最佳加筋方案.依据计算和试验所得结果,讨论了加筋体结构对路堤稳定性的影响.
