Abstract: There are many methods have been successfully used in the stability mitigation of high fill embankments. Due to its relatively matured theoretical design analysis procedures and its cost effectiveness, the geogrid is widely used in the high fill embankment as retaining structures. This paper discuss′ the three aspects in the embankment stability mitigations: 1) the effect of property variation of the subgrade soils 2) soil improvements; and 3) treatment of the embankment toe. The objectives of these discussions are to provide a safe and economical design scheme for the high fill embankments.
