... thresholds of several varieties of sandstones commonly used in architectural and sculptural projects. The modulus of resilience and modulus of toughness, computed from the respective parts of the stress-strain curves, proved to have a significant correlation between resistance to weathering...

... stiffness matrices and right hand sides and developed a finite element code for the calculation of rock deformations and stresses. The code was tested on several numerical examples. We computed in detail deformations and stresses in a round tunnel, first without any rock bolts and then with rock bolts...

... fault zone system was encountered. Its impact on the layout of the MFS Faido is described and the excavation procedures and the rock support measures as well as the extensive geotechnical computations are explained. After coping with the challenges of the difficult geology and the complex layout the MFS...

... of the BE and CN steps. To make this comparison computationally cheap, we shall use only the residual corresponding to the substitution of the BE time step solution I! into the CN equation, rj =(M0.56tjKrj -(M " -0.5MjKJ-' -0.5qj, -0.5qt'. Then the CN step increment can be approximated by the approximate value !CN...

For obvious reasons the geological model taken for the analysis at that time could not be so detailed as at the recent period, when excavation...

... diagrams. Fuzzy partitioning algorithms have been applied to discontinuity orientation data, and membership levels - representing "degree of certainty" - are computed directly from the data without the use of an assumed analytical function. These membership values are then directly used in the computation...

... to a reference event. The reference event is usually located by the classical hodogram method, but all the other doublets are localised with respect to it by computing their relative angle and distance differences. Among a class of doublets, the reference event is the event with the best signal to noise ratio...
