摘　　要：在高液限土地区,充分利用这类土质资源修筑路堤能够有效提高公路建设的经济效益。结合高液限土路堤特殊的工程性质,运用拉格朗日有限差分法软件FLAC,对不同路堤填筑方案处治后的变形特征进行模拟,并对路堤的变形及处治效果做出评价,为采用合理的处治措施提供依据。In the area of high liquid limit soil, taking full advantage of this kind of soil can effectively enhance the economic benefits of highway construction. Combined with the special nature of the high liquid limit soil embankment, the Lagrangian finite difference method software FLAC is used to simulate the deformation characteristics of different embankments treated with different programs. Then the deformation of the embankment and treatment effects are assessed, which can provide a basis for the use of the reasona- ble measures.
