Modelling and Simulation of Complex GeoTechnical Problems

چکیده
An extensive finite element analysis of stability of mining openings at the uranium mine GEAM D. Rož́ınka was firstly performed in the years 1996-2002, see Fig. 1. The final conclusions of this analysis advocate the use of a new mining technology (underhand stoping) and safety of mining in greater depths 950-1100 meters under the surface. At present, due to the price increase of the uranium, the GEAM mine prolonged its production life. New plans assume mining at depths up to 1200 meters, see [10]. After a detailed exploration at deeper levels and design of a new production project a new extensive finite element modelling is expected to be performed in the years 2009-2010.

Middleware-based Modelling and Simulation of Geotechnical Structures
Modern large scaled buildings are erected on rather complex foundations. The design and analysis of these geotechnical systems requires a high quality of computer modelling and simulation. Therefore, it is necessary to model all geotechnical structural elements in a realistic and practice-oriented way. Due to the complexity of geotechnical structures object-oriented models are most appropriate....
متن کاملGeotechnical Modelling of the Behaviour of Piles
Comprehensive geotechnical modelling of the behaviour of piles generally encounters setbacks: in preparing model bed simulating field conditions, of specific and uniform shear strength, and reproduction for repetitions. Due to such limitations in traditional practices, information on the complex mechanism of shaft-base resistance interaction is not adequately known. Other outcomes are: varied r...
متن کاملArtificial Neural Network Applications in Geotechnical Engineering
Over the last few years or so, the use of artificial neural networks (ANNs) has increased in many areas of engineering. In particular, ANNs have been applied to many geotechnical engineering problems and have demonstrated some degree of success. A review of the literature reveals that ANNs have been used successfully in pile capacity prediction, modelling soil behaviour, site characterisation, ...
