In order to make full use of industrial waste-fly ash,the article explores geogrid reinforced mechanism,carries out indoor model test for unreinforced,one-story reinforced,and two-story reinforced fly ash,simulates in-situ reinforced embankment deformation condition,and then qualitatively tests the relation curve between vertical pressure P and slope top settlement value S in the experiment,and finally sets up testing points at different location of model embankment,and measures their displacement condition,internal stress distribution,and development of reinforced embankment under load.In the end,it qualitatively analyzes the deformation of internal reinforced embankment,which has provided guidance for the application of fly ash reinforced embankment.%为充分利用粉煤灰这一工业废物,探讨了土工格栅加筋机理,对无筋、一层加筋、二层加筋的粉煤灰路堤进行了室内模型试验,模拟现场加筋路堤的变形情况,定性测定了在试验过程中所施加的竖向压力P与坡顶沉降值S的关系曲线;在模型路堤的不同位置布置测试点,量测加筋路堤在荷载作用下各测试点位移情况,内部应力分布、发展情况,定性分析了加筋路堤内部的变形性状,为粉煤灰加筋路堤的应用提供指导。
