【摘要】 |
|
An extensive test program was conducted on East China deep clay to investigate mechanical behavior in the process of axial compression and triaxial compression. In addition, the effect of negative temperature and confining pressure on the strength of frozen clay was analyzed. It is concluded that the stress-strain curves at high confining pressure belong to the strain hardening type and its strength almost corresponds to confining pressure in the range of tested confined stress. With respect to temperature, the strength increases when the temperature decreases. |
