Slaking of solid clays and claystones under hydraulic and mechanical action / Zerfall von festen Tonen und Tonsteinen bei hydraulischer und mechanischer Beanspruchung
Abstract:In tunnel drives with slurry‐supported face in semi‐solid to solid clay and claystone, hydraulic and mechanical actions can lead to the slaking of the excavated soil aggregates. Heavy slaking can lead to laborious separation associated with high cost. For investigations as preparation for a project, two test rigs were developed at the Zentrum Geotechnik of the TU München. These can be used to investigate slaking both phenomenologically in series tests and also on a large scale. Investigations on solid clays an… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
