Even though the model presented in this paper requires further refinement and improvement, FLAC modeling offers a promising approach for the evaluation of geosynthetic reinforcement above sinkholes where strains within the overlying materials is of concern, such as landfill liners in this case. The flexibility of FLAC is illustrated in this paper in application to static evaluation in homogenous soil. It is anticipated that FLAC models similar to the one presented in this paper can be applied to more complex conditions such as various sinkhole configurations (e.g., circular), layered soils, seepage, and/or seismic motions.
