Abstract

The region size to be treated by the 2-dimensional finite element method is one of the serious issues in Geotechnical Engineering since the simulated value of displacement strongly depends upon the depth of the allocated domain. In this paper, the reason for such a fact is firstly clarified by using the 3-dimensional boundary element method and some numerical examples of the tunnel excavation are illustrated to show how the domain size affects the results. Finally some remedies for the problem are proposed by assuming the oaring elastic modulus with the depth.
