The thesis contains a study on the apparent low friction in the motion of rock avalanches. A literature review is followed by the description of three real cases of rock avalanches. Then a report is presented, on laboratory work with an innovative high pressure rheometer, used in order to study the rheology of a fragmenting flow of rock granules. A developed numerical distinct elements model of the fragmentation rheometer is then described and its results are presented and discussed.

Abstract

The thesis contains a study on the apparent low friction in the motion of rock avalanches. A literature review is followed by the description of three real cases of rock avalanches. Then a report is presented, on laboratory work with an innovative high pressure rheometer, used in order to study the rheology of a fragmenting flow of rock granules. A developed numerical distinct elements model of the fragmentation rheometer is then described and its results are presented and discussed.
