ABSTRACT
A series of triaxial tests were performed on large specimens of a very dense well-graded gravel to study into the viscous property. A considerably large amount of drained creep deformations were observed at creep stages during shearing. The creep behaviour was essentially the same between partially and fully saturated specimens. Creep strains became larger as the stress state approached the failure state, despite that such behaviour of very dense gravel has been often ignored in geotechnical engineering practice. The observed viscous behaviour could be reasonably simulated by one of the three-component rheological models, called the general TESRA model. Effects of stress path and the viscous property on the flow characteristics are discussed.
