Course. Characterization of rock masses in large undertakings
Formation
SCOPE AND OBJECTIVES
The evaluation of the geomechanical parameters of rock masses in large projects is a topic of great importance given the geological complexity of the massifs and the difficulties in their evaluation. The difficulties are related to the uncertainties associated with the rock mass, whose characterization is normally carried out through in situ and laboratory tests, complemented by the use of empirical systems.
The Faculty of Engineering of the University of Porto (FEUP) will organize an Intensive Course on Characterization of Rocky Massifs in Large Undertakings, with a particular focus on geometric characterization, testing and the use of empirical systems and Data Mining techniques. A technical visit to the Venda Nova III hydroelectric scheme, by EDP – Gestão da Produção de Energia S.A., is planned.
The course will be taught by Luís Ribeiro e Sousa and Celso Lima from FEUP, Manuel Oliveira, Carlos Esteves and Nadir Plasencia, from EDP. They are specialists in the field of underground works, in large projects. The course will be in a hybrid format, online or presential format.
