of a modified Cam-clay model is incapable of predicting the lateral deformation
of foundation beneath an embankment.
The measured results showed that the settlement was still in progress,
whereas the time-independent version of model did not predict the creep
behavior. Thus, the time-dependent version of the proposed model should be
incorporated into the analysis following the refinement of numerical scheme.
6 SUMMARY AND CONCLUSIONS
A waste containment dike constructed over soft clay foundation was analyzed. A
set of field instrumentation results was compared to the results of analysis. The
comparison showed that the agreement between the analysis and measurements
was satisfactory. However, the analysis underestimated the horizontal
displacement, especially for the isotropic model. The importance of simulating
the anisotropic behavior of soils was highlighted in this analysis.
The results of this study, as summarized here, should be considered as an
initial attempt to the application of the anisotropic version of bounding surface
model to embankment constructed over soft foundations. The time-dependent
version of the proposed model should be incorporated into the analysis following
the refinement of the numerical scheme.
