中文摘要：

通过有限元模拟，对不同土石方比例、压实状态下，倒装填筑结构路堤的稳定性进行分析，得到了一些有价值的结论，以期对将来的路堤建设中提供一种可借鉴的方法。其研究表明：在倒装结构路堤中下层填土层的高度控制在10m范围以内，路堤边坡稳定安全系数较大（大于1．4），且能满足工程上设计要求；通过对路基基底、填土层和填石层的压实度提出了不同的要求和处理措施，足以保证整体结构的稳定性。

英文摘要：

By using FEM simulation, the stability analysis is carried out for the inversive filling structure embankment in different earth-rock proportion and compaction degree to get the valuable conclusions which could provide a referable method for the future construction of embankments. The results show that the height of the earthfill would be controlled within a range of 10 meters, the slope stability safety factor would be larger（larger than 1.4）, which could satisfy the requirements of engineering design; The different requirements and measures proposed in the compaction degree of foundation, earthfill and rockfill could perfectly ensure the stability of overall structure.
