Parameterised mesh generation for finite element analysis of tunnelling
Donaldson Associates Ltd, Charles E. Augarde · 2008
The use of three-dimensional (3D) finite element (FE) models for geotechnics is increasing, particularly for the simulation of the progressive excavation and lining of a tunnel (or tunnels), including features such as underground services, or surface structures and loading. A major overhead in the use of 3D FE models is meshing and this is particularly so for tunnelling schemes due to the geometries involved. This paper introduces a parameterised scheme for automated 3D mesh generation of highly complex tunnelling layouts using a freeware mesh generator. Comparisons are made with meshers found in commercial FE software.
