ABSTRACT

The inherent variability of rock mass is difficult to take into account and for this reason engineers very often solve the question “What value should be used in analyses?”. The answer on such question requires a probabilistic approach in the evaluating the uncertainty in the input parameters in geologic media. In the recent time specialists encounter problems of the input parameters in using uncertainty modelling based on the Fuzzy set theory, Monte Carlo Simulation, Latin Hypercube Sampling etc.
