Geosynthetic Reinforced Containment Dike Constructed over Soft Foundation: Numerical Analysis

This chapter analyzed a waste containment dike that was constructed over a soft clay foundation. A set of field instrumentation results were compared to the results of the analysis and 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 also highlighted in the chapter. The results of the study, as summarized in this chapter, should be considered as an initial attempt to the application of the anisotropic version of the bounding surface model to the 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.
