A téma rövid leírása, a kidolgozandó feladat részletezése:

There are several cities in Hungary such as Eger, Budafok, Castle hill of Buda and in other part of the world as well such as Paris, Rome where the ancient underground cellars and cavities cause problems. These problems are mostly related to the existing buildings or development of the area. The investigations of these underground cellars started many decades before. The numerical methods which are commonly used for engineering geological problems can be also used for stability analysis of these cavities and for the investigations of the relations between cellar stability and landslides. According to previous experiences the design of the support system of these cellars were made by empirical methods. For more efficient and economical solution detailed investigations and calculations are needed.

The task of the PhD student is to determine the input parameters of numerical modelling with using of the results of in situ and laboratory investigations (for example: parameters of joints, rock mass properties, UCS values in dry and water saturated condition). Furthermore, part of her/his task also the analysis of the factors influencing the stability of the cavities with 2D and 3D numerical methods. For modelling of the cavities the Rocscience software package is available at the department.

The in-situ, laboratory and numerical investigations provides useful results for the international practice as well about the old underground structures and about the protection against the hazards caused by these cavities.
