ABSTRACT

Two different case studies are presented showing the application of the discontinuum modelling technique for slope stability analysis and for predicting the rock support in a tunnel in Western Norway. The first study evaluates the static and dynamic stability of a 700 m high rock slope in the West of Norway. This study has helped in estimating the volume of the rock mass that could potentially slide under the simulated static and dynamic forces. This estimation was required to assess the run-up heights (tsunami) in a fjord that could potentially be caused by the rockslide.

The second numerical discontinuum study predicts the performance of different types of rock support in a sub-sea tunnel in the West of Norway. This was required for optimising the support in a tunnel. Both the case studies provide an illustration of how the geo-mechanical properties of a rock mass can be integrated in a numerical discontinuum model, which is used for predicting the behaviour of both the rock slope and the support in a tunnel.
