For each simulated sample function representing field test results it corresponds one set of soil constitutive parameters, representing stochastic input for one finite element simulation (Fig. 1c). The numerical computations are performed using the code DYNAFLOW (Prevost (1995)), which is a finite element analysis program for static and transient response of linear and nonlinear two- and three-dimensional systems. The Monte Carlo simulation results are provided in terms of a range of predictions, as shown in the next section. Providing that the number of sample functions is sufficiently large, the statistics of structural response can be inferred.
