PREDICTION OF LONG TERM DEFORMATION OF A COMPACTED COHESIVE SOIL EMBANKMENT OVER A SOFT FOUNDATION

The study is concerned with prediction of the long-term deformation of a compacted cohesive soil embankment over a soft foundation. The prediction of embankment performance was made using the finite element method of analysis incorporating a nonlinear viscoelastic model of the fill behavior and a quasielastic representation of the foundation. A full-scale test embankment was constructed and instrumented to permit evaluation of the predictive approach. Samples of subsurface and the embankment material were tested in the laboratory to determine numerical values of desired material parameters. The performance of the test embankment was monitored both during and after its construction.
