【 摘 要 】

The stability of road embankment on soft ground is always the highlight during construction. Usually the construction is carried out on the reinforced ground and the degree of reinforcement is influenced by the methods and period. In order to evaluate such influence, changing the compression index is a simple way to represent it. Also the service load can be represented by assigning different bulk density of surcharge. Finite element strength reduction method is used to evaluate the stability of embankment at different stages.
