The performance of embankments resting on soft soil subgrades is of practical interest to all the engineers. Soil reinforcement techniques have come in to practice to improve the performance of these structures. With the recent development of sandwich technique (so called because the reinforcement ii;; sandwiched between two strong soil layers), it is possible to use locally available materials for the construction of these structures. This paper discusses the finite element techniques that can be adopted for the analysis of such structures and an advanced constitutive models for simulating the performance of soils. The paper will also present several results obtained from parametric finite element analysis of reinforced soil embankments constructed of clay soils using sandwich technique.
