A methodology is developed to compare different design alternatives of a cavity system. The performance of each alternative is evaluated according to six independent criteria representing the behavioral mode of the cavity system under a seisme. The computational part of the study is based on a two-dimensional Finite Elements uncertainty analysis and provides the quantification of the above-mentioned criteria. An inference model links together the statistical data of the important physical parameters obtained from a site investigation and the main analytical model which possesses four computational steps; namely the evaluation of the effects of: (1) an underground waterflow on the rock lmedia; (2) the excavation on the rock media; (3) a seismic perturbation on the rock media; (4) the displacement of the rock media on the liner. The rock media is assumed to be isotropic both in the physical and statistical sense. Computations are performed for each design alternative, in a two-dimensional geometric framework using triangular and beam type Finite Elements. /FHWA/
