Elaboration of hydromechanical coupled models by interpretation of the disturbances observed during the sinking of the main shaft of an underground laboratory in eastern France

Objective

An instrument array will record the rock mass response during shaft sinking for an underground research laboratory in Eastern France in a deep argillite formation. This kind of geological formation is considered as a potential host rock for a radioactive waste repository. The proposed MODEX-REP project consists in: development of the constitutive models by analysing surface laboratory tests results; prediction of the rock mass response to shaft excavation; analysis of the results of in-situ measurements; comparison of the prediction with the measured rock mass response; and validation of the models. The relevance of the constitutive models for predicting rock mass hydromechanical behaviour will be evaluated through the comparison. The models validated by in-situ testing at natural scale will enhance public confidence in prediction capacity. Shaft excavation is not included financially in the proposed project.
