Abstract [en]

The design following EC7 must be based on a combination of calculations, prescriptive measures, experimental model and observational method. The observational method must rely on the best design that can be done in advance taken in account all prevailing uncertainties, aleatoric or epistemic. In rock mechanics, as we don't usually know the state of stress or strain in the rock, active or interactive design shall rely on the deformations measures aswell as on good knowledge of the geology and structure of the rock mass to define limit states. The peculiarities due to rock mechanics in the enforcement of the observational method are emphasized. Some directions for active design will be given to better define the method and insure safe design.
