Abstract In underground excavations, the shape of the opening is of main concern due to its impact on the stress distribution around the opening. However, because of the complex and non-linear behaviour of soil only a few works have dealt with this problem. In this paper an evolutionary structure optimization (ESO) procedure is used for optimizing the shape of underground excavations in a cohesive frictional material obeying Mohr-Coulomb material model. The presented examples show the capability of ESO method in tackling such problems.
