I have received some triaxial CIU test results, and the stress path indicates that the samples contracted until 7 to 10% strain, then started to dilate. The deviator stress continued to increase even after the pore pressure reached its peak.
Is it reasonable to consider peak effective shear...
The next step is to obtain samples and define the critical state properties using triaxial test. My question was more focused if there is any difference to define the contractive/dilative behaviour of a soil and the transition between them depending only if it's sand or clay.
The state parameter...
Hi everyone,
I usually process CPT data to estimate the state parameter and define if the soil is contractive or dilative. However in my last project I was told that I should consider undrained parameters (USR) to characterize a embankment built enterally with cohesive clay that showed...
