A téma rövid leírása, a kidolgozandó feladat részletezése:
In case of rock slope stability analyses there are many kinds of uncertainties that significantly influence the outcomes. Usually the discontinuities are widely scattered and variable thus their characteristic cannot be properly represented by single value, and all other petrophysical property has a high deviation along a large slope. Thus the evaluation contains the uncertainties of the input parameters, the uncertainties of the calculation, and the procedure as well. The probabilistic approach provides a flexible tool for engineers to design the slope angles or the support system based on the significance of the project or the required confidence level. However there is no widely used and accepted value for the probability of failure or other acceptance criteria. The evaluation of the risk is really different according to the literature data since the consequence of a failure can be different in the view of the scale, the costs, the environmental impact or the safety of the people. Therefore the standards still demand deterministic calculations and safety factors however it might results a higher uncertainty of the outcomes and creates an uneconomical solution.
The task of the applicant is to compare the results of the deterministic and probabilistic calculations in different cases and based on the results of the calculations and the collected data work out an acceptance criterion or more for different situations.
