RELIABILITY ANALYSIS OF UNDERGROUND STRUCTURES USING FEM

Popis výsledku v původním jazyce

The behaviour of a geomechanical model and its final results are strongly affected by the input parameters. As the inherent variability of rock mass is difficult to model, engineers are frequently forced to face the question "Which input values should beused for analyses?" The correct answer to such a question requires a probabilistic approach, considering the uncertainty of site investigations and variation in the ground. This paper describes the statistical analysis of input parameters for FEM calculations of traffic tunnels in the city of Prague. At the beginning of the paper, the inaccuracy in the geotechnical modelling is discussed. In the following part the Fuzzy techniques are summarized, including information about an application of the Fuzzyarithmetic on the shotcrete parameters. The next part of the paper is focused on the stochastic simulation - Monte Carlo Simulation is briefly described, Latin Hypercubes method is described more in details.
