NUMERICAL MODELLING FOR UNDERGROUND MINING RELATED GEOTECHNICAL ISSUES

Numerical Modelling of the Segmental Lining of Underground Structures

There are several methods for analysing the behaviour of underground structures under different loading conditions. Most of these methods have many simplifications; therefore, in some cases, the results are too conservative and a very high safety factor, usually of more than 2 is needed. On the other hand, for stability analysis and the designing of support systems, these methods consider segme...

Modelling issues for numerical analysis of deep excavations

The influence of different modelling assumptions on the results of numerical analyses of a deep excavation problem is discussed. Based on a reference solution a comprehensive parametric study is performed, identifying modelling assumptions which may have a significant influence on the calculated displacement behaviour and the bending moments in the wall. The parameters investigated include wall...
