Abstract
It was clarified that the strength and deformation properties of geo-materials depended on strain rate, and the characteristics or degree of the dependency varied in response to the viscous property of the materials. To investigate the effect of strain rate on strength and deformation properties of cement-treated clay with high strength, a series of triaxial compression tests was conducted while strain rate was changed stepwise by a factor of up to 1000 in each test.
The stress-strain relationship at a certain level shifted to that of higher/ lower level after indicating high stiffness and subsequent yielding, when the strain rate suddenly increased/ decreased. [This abstract is not included in the PDF]
