Resumo(s)This paper addresses the performance analysis of an optimization algorithm from the field of evolutionary computation, namely an Evolution Strategy, in back analysis to evaluate the geomechanical parameters of the formation surrounding an underground structure. The algorithm is first tested using a synthetic case of a tunnel excavation. In this case, different scenarios are considered through a parametric study. Then the algorithm is tested using real data from the excavation of an underground structure built in the North of Portugal using a 3D model. The results show that the Evolution Strategy algorithm is robust in the identifica-tion of geomechanical parameters related to underground engineering.
