Abstract

The aim of the paper is to present a novel approach for the analysis of underground excavation problems. Non-Uniform Rational B-Spines (NURBS) are used for the description of the geometry and for the approximation of the unknowns. The resulting equation system with the IGABEM has much fewer unknowns than conventional BEM approaches and an excellent solution quality is obtained. NURBS are also used for the geometrical description of geological inclusions, which can have properties different to the surrounding rock mass and can exhibit inelastic material behaviour. This will be domonstrated on a practical example in geomechanics, a 3-D simulation of a cavern excavation of a hydropower station.
