ABSTRACT: When the geotechnical engineer is involved in rock mass characterisation, he is faced with geological and geotechnical data which inherently contain uncertainties. This paper proposes a procedure to facilitate the processing of these data, and to consistently consider uncertain parameters in the geotechnical design process. Consequences on the requirements for geological investigations and modelling are discussed. The general procedure of rock mass characterisation and its computational implementation is described whereby the focus is set on probabilistic processing of geological data. The application of the procedure is presented in detail on a rock mass characterisation performed for a major tunnel project in Austria.
